Pillar CZ 455/457 Slim Helix Knurled Bolt Knob – Black
The Pete's Pillars PP4HK Slim Helix Knurled Bolt Knob combines distinctive machining, a textured gripping surface, and lightweight billet aluminum construction in a streamlined design for CZ 455 and CZ 457 rifles.
Precision CNC-machined in the USA, the PP4HK features a helix-inspired profile with knurled exterior detailing, delivering a comfortable gripping surface without the bulk of an oversized competition bolt knob.
Whether you're refining a factory CZ 457, building a precision rimfire competition rifle, or simply looking for an attractive replacement bolt knob, the PP4HK offers a practical blend of ergonomics and craftsmanship.
Distinctive Helix Knurled Design
The PP4HK stands apart with its machined helix contours and knurled gripping surface, combining flowing geometry with functional texture.
The knurling provides tactile feedback, while the slim profile maintains a balanced appearance on the compact CZ rimfire action.
For shooters who appreciate precision machining without an overly large bolt knob, the Helix design offers a distinctive alternative to conventional round and cylindrical profiles.

Precision CNC-Machined Billet Aluminum
Manufactured from solid billet aluminum, the PP4HK delivers lightweight construction, precisely machined exterior details, and a clean black finish.
The aluminum construction provides an attractive balance of weight and durability, while the carefully machined profile complements factory CZ rifles and aftermarket chassis systems.
Like our other American-made bolt knobs, the PP4HK reflects Pete's Pillars' emphasis on thoughtful design and quality machining.
Designed for CZ 455 & CZ 457 Rifles
The PP4HK is designed as a replacement bolt knob for compatible CZ 455 and CZ 457 threaded bolt handles.
Its slim dimensions and knurled exterior make it an attractive choice for target shooting, competition, hunting, and recreational use.
Verify your existing bolt handle's threading and compatibility before ordering. This product is a replacement knob rather than a complete bolt handle assembly.
