PETE'S PILLARS | PRECISION CZ RIMFIRE COMPONENTS
Two Stainless Screws. One Less Thing to Worry About.
Whether you're replacing worn factory hardware or refreshing a favorite rimfire rifle, our PP45748 Stainless Steel Barrel Set Screws give your CZ 455 or CZ 457 a clean, corrosion-resistant replacement. Each set includes both barrel retaining screws, with the familiar 3mm internal hex drive and direct factory-hardware fit.
The CZ 455 and CZ 457 are popular rifles for good reason, and their barrel-retaining hardware is an important detail worth getting right. Our PP45748 two-screw set replaces the original steel barrel screws with stainless components that look sharp and hold up well to regular range days, field use, and routine maintenance.
These are the screws used at the receiver to retain the barrel—not the action screws that fasten the rifle into its stock. They're a straightforward replacement for damaged, missing, or aging originals, and a handy spare set for anyone who spends time working with CZ rimfire rifles.
Stainless Steel. Factory-Style Fit.
Corrosion-resistant stainless steel gives these barrel screws lasting appeal, with a clean finish that contrasts nicely against the receiver. The 3mm internal hex drive keeps the familiar interface of the original hardware, so you're not switching to an unusual screw-head style just to replace a small but essential part.
PP45748 is a replacement for CZ OEM part number 309913006011, identified as #48 in the applicable parts diagram. The set includes two screws—the quantity needed to replace the pair of factory barrel retaining screws. No trimming or custom machining is required for compatible factory applications.
Made for CZ 455 and CZ 457 Shooters
These screws fit the compatible factory barrel-retaining interfaces on CZ 455 and CZ 457 rifles. For CZ 457 owners, that includes the familiar factory caliber configurations such as .22 LR, .17 HMR, and .22 WMR. Whether your rifle sees squirrel woods, a bench, or a rimfire match, this is the kind of small replacement part that's worth having in the parts drawer.

Frequently Asked Questions
What's included, where these screws go, and which CZ rifles they fit.
Do these barrel screws fit both the CZ 455 and CZ 457?
Yes. PP45748 fits compatible factory CZ 455 and CZ 457 barrel-retaining interfaces. You get two stainless replacement screws in the package.
Is PP45748 the replacement for CZ part 309913006011?

How many screws come in the package?
Two. You get both barrel set screws, not just a single replacement.
What size hex wrench do these use?
They have a 3mm internal hex drive, matching the familiar factory-style screw head.
Are these barrel screws or action screws?
Barrel screws. These retain the barrel at the receiver. If you need the screws that secure the action in the stock, look at our PP457DS drop-in or PP457AS custom-fit action screw sets.
Will they work with .22 LR, .17 HMR, and .22 WMR CZ 457 rifles?
Yes. For compatible factory CZ 457 rifles, the barrel set screw application is the same across these caliber configurations.
Do these need to be cut or fitted before use?
