PETE'S PILLARS BEDDING HELPER HARDWARE | M5 × 0.8 METRIC
The Hardware That Belongs with Your CZ 457 Pillars.
Our Pete's Pillars Bedding Helper Hardware Kit M5 × 0.8 is companion hardware for CZ 457 pillar bedding work. Built around the correct metric action screw thread, it gives you a dedicated option for keeping the action and bedding pillars aligned during a stock bedding project.
From a factory wood or laminate stock to a rifle-specific aftermarket inlet, successful pillar bedding starts with the right fit. Select the Pete's Pillars Competition or SlimLine set for your stock, then add the M5 × 0.8 helper hardware for the matching CZ 457 screw pattern. Use it for: CZ 457 stock bedding, pillar positioning, stock replacement projects and custom bedding setups.
Thread-Matched to the Action.
The rifle inlet and the action screw thread answer two different questions. The inlet determines the shape and dimensions of the bedding pillars; the threaded action determines which helper hardware belongs with the job. This is the M5 × 0.8 companion option for CZ 457 projects—not an M6 kit, and not a finished replacement action screw set.
Common CZ 457 Rifle & Stock Inlets
The M5 × 0.8 helper hardware is intended for CZ 457 actions. These are mainstream CZ 457 rifle and stock configurations you'll see in pillar bedding projects; the correct pillar style still depends on the actual stock.
Classic sporting stock profiles, including wood-stock bedding and replacement-stock projects.
Heavy-barrel and match-oriented stock configurations, including the MTR family.
Factory configurations with distinct stock geometry; choose the pillar kit for the inlet in front of you.
Compatible CZ 457-specific Boyds, Manners, McMillan and other aftermarket stocks when pillar bedding is appropriate.
Pair It With the Right Pete's Pillars Set.
Our profiled pillars are rifle-specific; this hardware is thread-specific. Choose the bedding set that fits your CZ 457 stock. Add the helper hardware alongside it as a separate companion item.

Frequently Asked Questions
Choosing the correct thread and matching hardware to your CZ 457 stock.
Which rifle inlets use the M5 × 0.8 kit?
This kit is intended for CZ 457 actions in American, Lux, Royal, Varmint, Varmint MTR, Pro Varmint, AT-ONE, Scout and compatible CZ 457-specific aftermarket stock inlets. Confirm your stock design and threaded interface before selecting the companion hardware.
Will it fit a CZ 455 or CZ 452?
Don't use the CZ 457 inlet as a substitute for CZ 455 or CZ 452 fitment. Those actions have their own pillar geometries, and the hardware must match the actual action screw thread. We also offer M6 × 1.0 helper hardware for separately confirmed M6 applications.
Can I pair it with Competition and SlimLine pillars?
Yes. Choose Competition or SlimLine pillars based on the CZ 457 stock and available material. This M5 helper hardware is a separate companion to those bedding products.
Does this kit include the bedding pillars or epoxy?
Your Choice: profiled bedding pillars and bedding epoxy are sold separately. For a CZ 457 option with epoxy, see our Competition Pillar Kit with Epoxy; the epoxy brand may vary.
Does the helper kit replace my finished action screws?
No. It's hardware for the pillar bedding project. For final action hardware, we offer our PP457AS trim-to-fit replacement action screws separately.
What about Boyds, Manners, McMillan or other aftermarket stocks?
The name on the stock doesn't determine the thread pitch. This helper kit is matched to the CZ 457 M5 × 0.8 action screw interface. Choose a CZ 457-specific stock inlet and the corresponding bedding pillar profile for that stock.
What's the difference between M5 × 0.8 and M6 × 1.0?
They are different metric thread sizes and aren't interchangeable. The CZ 457 companion kit is M5 × 0.8. The M6 × 1.0 hardware kit is for rifles whose action screws use M6 × 1.0. Confirm the thread specification rather than choosing by appearance.
Small Change. Big Impact. Pete's Pillars.

<details class="pp-accordion-item"><summary>Which rifle inlets use the M5 × 0.8 kit?</summary><div class="pp-accordion-answer"><p>This kit is intended for CZ 457 actions in American, Lux, Royal, Varmint, Varmint MTR, Pro Varmint, AT-ONE, Scout and compatible CZ 457-specific aftermarket stock inlets. Confirm your stock design and threaded interface before selecting the companion hardware.</p></div></details>
<details class="pp-accordion-item"><summary>Will it fit a CZ 455 or CZ 452?</summary><div class="pp-accordion-answer"><p>Don't use the CZ 457 inlet as a substitute for CZ 455 or CZ 452 fitment. Those actions have their own pillar geometries, and the hardware must match the actual action screw thread. We also offer <a href="https://www.petespillars.com/shop/petes-pillars-bedding-helper-hardware-kit-m6-x-1-0-36661" style="color:#007F9A;font-weight:700;text-decoration:none;">M6 × 1.0 helper hardware</a> for separately confirmed M6 applications.</p></div></details>
<details class="pp-accordion-item"><summary>Can I pair it with Competition and SlimLine pillars?</summary><div class="pp-accordion-answer"><p>Yes. Choose <a href="https://www.petespillars.com/shop/pete-s-pillars-cz-457-competition-pillar-kit-36599" style="color:#007F9A;font-weight:700;text-decoration:none;">Competition</a> or <a href="https://www.petespillars.com/shop/pete-s-pillars-cz-457-slimline-pillar-kit-18093" style="color:#007F9A;font-weight:700;text-decoration:none;">SlimLine</a> pillars based on the CZ 457 stock and available material. This M5 helper hardware is a separate companion to those bedding products.</p></div></details>
<details class="pp-accordion-item"><summary>Does this kit include the bedding pillars or epoxy?</summary><div class="pp-accordion-answer"><p>Your Choice: <a href="https://www.petespillars.com/shop/category/pillars-74" style="color:#007F9A;font-weight:700;text-decoration:none;">profiled bedding pillars</a> and bedding epoxy are sold separately. For a CZ 457 option with epoxy, see our <a href="https://www.petespillars.com/shop/ppcd-s-pete-s-pillars-cz-457-competition-pillar-kit-with-epoxy-18047" style="color:#007F9A;font-weight:700;text-decoration:none;">Competition Pillar Kit with Epoxy</a>; the epoxy brand may vary.</p></div></details>
<details class="pp-accordion-item"><summary>Does the helper kit replace my finished action screws?</summary><div class="pp-accordion-answer"><p>No. It's hardware for the pillar bedding project. For final action hardware, we offer our <a href="https://www.petespillars.com/shop/pp457as-cz-457-custom-cnc-machined-premium-replacement-action-screws-pp457as-34019" style="color:#007F9A;font-weight:700;text-decoration:none;">PP457AS trim-to-fit replacement action screws</a> separately.</p></div></details>
<details class="pp-accordion-item"><summary>What about Boyds, Manners, McMillan or other aftermarket stocks?</summary><div class="pp-accordion-answer"><p>The name on the stock doesn't determine the thread pitch. This helper kit is matched to the CZ 457 M5 × 0.8 action screw interface. Choose a CZ 457-specific stock inlet and the corresponding bedding pillar profile for that stock.</p></div></details>
<details class="pp-accordion-item"><summary>What's the difference between M5 × 0.8 and M6 × 1.0?</summary><div class="pp-accordion-answer"><p>They are different metric thread sizes and aren't interchangeable. The CZ 457 companion kit is M5 × 0.8. The <a href="https://www.petespillars.com/shop/petes-pillars-bedding-helper-hardware-kit-m6-x-1-0-36661" style="color:#007F9A;font-weight:700;text-decoration:none;">M6 × 1.0 hardware kit</a> is for rifles whose action screws use M6 × 1.0. Confirm the thread specification rather than choosing by appearance.</p></div></details>

<p class="pp-hero-eyebrow">PETE'S PILLARS BEDDING HELPER HARDWARE | M5 × 0.8 METRIC</p>
<h2>The Hardware That Belongs with Your CZ 457 Pillars.</h2>
<p class="pp-hero-copy">Our <strong>Pete's Pillars Bedding Helper Hardware Kit M5 × 0.8</strong> is companion hardware for CZ 457 pillar bedding work. Built around the correct metric action screw thread, it gives you a dedicated option for keeping the action and bedding pillars aligned during a stock bedding project.</p>
</section>
<p>From a factory wood or laminate stock to a rifle-specific aftermarket inlet, successful pillar bedding starts with the right fit. Select the <a href="https://www.petespillars.com/pillars-bedding" style="color:#007F9A;font-weight:700;text-decoration:none;">Pete's Pillars Competition or SlimLine set</a> for your stock, then add the M5 × 0.8 helper hardware for the matching CZ 457 screw pattern. <strong>Use it for:</strong> CZ 457 stock bedding, pillar positioning, stock replacement projects and custom bedding setups.</p>
<h2 style="font-size:22px;color:#171A1D;margin:28px 0 12px;">Thread-Matched to the Action.</h2>
<p>The rifle inlet and the action screw thread answer two different questions. The inlet determines the shape and dimensions of the bedding pillars; the threaded action determines which helper hardware belongs with the job. This is the <strong>M5 × 0.8</strong> companion option for CZ 457 projects—not an M6 kit, and not a finished replacement action screw set.</p>
<h2 style="font-size:22px;color:#171A1D;margin:28px 0 12px;">Common CZ 457 Rifle & Stock Inlets</h2>
<p>The M5 × 0.8 helper hardware is intended for CZ 457 actions. These are mainstream CZ 457 rifle and stock configurations you'll see in pillar bedding projects; the correct pillar style still depends on the actual stock.</p>
<div class="pp-fitgrid">
<div class="pp-fitbox"><strong>CZ 457 American, Lux & Royal</strong><p>Classic sporting stock profiles, including wood-stock bedding and replacement-stock projects.</p></div>
<div class="pp-fitbox"><strong>CZ 457 Varmint & Varmint MTR</strong><p>Heavy-barrel and match-oriented stock configurations, including the MTR family.</p></div>

</div>
<div class="pp-note"><strong>Fitment note:</strong> CZ 457 is the intended action family. A CZ 452 or CZ 455 is a different bedding inlet, and this M5 kit should not be selected for those rifles without verifying the actual action screw thread. Some factory or chassis stock systems already include their own bedding support and may not need additional pillars.</div>

<p>Our profiled pillars are rifle-specific; this hardware is thread-specific. Choose the bedding set that fits your CZ 457 stock. Add the helper hardware alongside it as a separate companion item.</p>

<details class="pp-accordion-item"><summary>Which rifle inlets use the M5 × 0.8 kit?</summary><div class="pp-accordion-answer"><p>This kit is intended for CZ 457 actions in American, Lux, Royal, Varmint, Varmint MTR, Pro Varmint, AT-ONE, Scout and compatible CZ 457-specific aftermarket stock inlets. Confirm your stock design and threaded interface before selecting the companion hardware.</p></div></details>
<details class="pp-accordion-item"><summary>Will it fit a CZ 455 or CZ 452?</summary><div class="pp-accordion-answer"><p>Don't use the CZ 457 inlet as a substitute for CZ 455 or CZ 452 fitment. Those actions have their own pillar geometries, and the hardware must match the actual action screw thread. We also offer <a href="https://www.petespillars.com/shop/petes-pillars-bedding-helper-hardware-kit-m6-x-1-0-36661" style="color:#007F9A;font-weight:700;text-decoration:none;">M6 × 1.0 helper hardware</a> for separately confirmed M6 applications.</p></div></details>
<details class="pp-accordion-item"><summary>Can I pair it with Competition and SlimLine pillars?</summary><div class="pp-accordion-answer"><p>Yes. Choose <a href="https://www.petespillars.com/shop/pete-s-pillars-cz-457-competition-pillar-kit-36599" style="color:#007F9A;font-weight:700;text-decoration:none;">Competition</a> or <a href="https://www.petespillars.com/shop/pete-s-pillars-cz-457-slimline-pillar-kit-18093" style="color:#007F9A;font-weight:700;text-decoration:none;">SlimLine</a> pillars based on the CZ 457 stock and available material. This M5 helper hardware is a separate companion to those bedding products.</p></div></details>
<details class="pp-accordion-item"><summary>Does this kit include the bedding pillars or epoxy?</summary><div class="pp-accordion-answer"><p>Your Choice: <a href="https://www.petespillars.com/shop/category/pillars-74" style="color:#007F9A;font-weight:700;text-decoration:none;">profiled bedding pillars</a> and bedding epoxy are sold separately. For a CZ 457 option with epoxy, see our <a href="https://www.petespillars.com/shop/ppcd-s-pete-s-pillars-cz-457-competition-pillar-kit-with-epoxy-18047" style="color:#007F9A;font-weight:700;text-decoration:none;">Competition Pillar Kit with Epoxy</a>; the epoxy brand may vary.</p></div></details>
<details class="pp-accordion-item"><summary>Does the helper kit replace my finished action screws?</summary><div class="pp-accordion-answer"><p>No. It's hardware for the pillar bedding project. For final action hardware, we offer our <a href="https://www.petespillars.com/shop/pp457as-cz-457-custom-cnc-machined-premium-replacement-action-screws-pp457as-34019" style="color:#007F9A;font-weight:700;text-decoration:none;">PP457AS trim-to-fit replacement action screws</a> separately.</p></div></details>
<details class="pp-accordion-item"><summary>What about Boyds, Manners, McMillan or other aftermarket stocks?</summary><div class="pp-accordion-answer"><p>The name on the stock doesn't determine the thread pitch. This helper kit is matched to the CZ 457 M5 × 0.8 action screw interface. Choose a CZ 457-specific stock inlet and the corresponding bedding pillar profile for that stock.</p></div></details>
<details class="pp-accordion-item"><summary>What's the difference between M5 × 0.8 and M6 × 1.0?</summary><div class="pp-accordion-answer"><p>They are different metric thread sizes and aren't interchangeable. The CZ 457 companion kit is M5 × 0.8. The <a href="https://www.petespillars.com/shop/petes-pillars-bedding-helper-hardware-kit-m6-x-1-0-36661" style="color:#007F9A;font-weight:700;text-decoration:none;">M6 × 1.0 hardware kit</a> is for rifles whose action screws use M6 × 1.0. Confirm the thread specification rather than choosing by appearance.</p></div></details>
