DIP Inc. CZ 452 American & Varmint 17HMR/22WMR Action Screws (19012)
TORX drive action screw “Kit” for the 452 American & Varmint chambered in 17HMR or 22WMR(magnum) with the factory steel magazine well. Makes repeating the action torque simple and easy. Designed for with the factory metal magazine well. Helps to eliminate the chance of slipping and marring the CZ wood stock because of the factory slotted screws.
When bench testing your CZ we recommend you start your action screw torque at about 18 inch pounds on the 2 action screws and work up from that point 2 inch pounds at a time until you find your best group size but no more then 32-34 inch pounds. The wood screw only needs to be snug. Our experience has found that a 20 inch pound torque seems to work well for the best group size with most available ammo.
Please check the factory action screw shaft length measured from the underside of the head:
1 – Wood Screw
1 – 13mm(.5”) Action Screw
1 – 27mm(1.06”) Action Screw
