This is a bag full of screws for the Holosun Red Dot sights and should cover most needs to fit on the Sig P365 line of pistols.
Three 6mm long sight mounting screws M3 - 0.5
Three 8mm long sight mounting screws M3 - 0.5
Three 10mm long sight mounting screws M3 - 0.5
Two Battery door screws (407k, 507K and 507C as well as many others)
We include three of each mounting screw so when you lose one on the floor you still have enough to mount your sight... (we've all been there and done that).
The mounting screws use a #10 Torx bit (available separately) for install.
The battery door screws use a 1.3mm Allen Key
