Fits CZ-453 American and Varmint, chambered in 17 HMR and 22 WMR
Action Screw Kit
This Action Screw Kit has all the screws and features a #20 Torx(star) head driver and bit. These are high quality and custom machined in the USA. The head design is such that the screws fit almost 100% perfectly flush with the trigger guard. The star(Torx) drive allows better drive contact area for a non-slip drive every time with minimal wear on the screw and driver bit.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 shaft length of your screws before making your selection:
Action Screw 1.26" (32mm)
Action Screw .5" (13mm)
Wood screw.
