Product Description
1/2" UNC High Tensile Cup Point Socket Grub Screws – Self Colour
These 1/2"-13 UNC socket grub screws provide a compact fastening solution for securing components such as shaft collars, pulleys, gears and knobs. Manufactured from hardened high tensile alloy steel, they feature a cup point and an internal hexagon socket drive.
The headless design allows the screw to sit flush with or below the surface of a suitably threaded component. The cup point concentrates contact around its rim, helping the screw grip the mating surface.
