Square Head Set Screws

Square head set screws give you a solid wrenching surface when an Allen key is not in the cards. These case-hardened, cup point screws bite into shafts and collars to stop slip and hold torque. Choose plain heads for standard installs or drilled heads for safety wire and lockout insurance. ASME B18.6.2.
