About Shoulder Screws

The smooth barrel below the head allows parts to rotate around or glide along these screws. Also known as shoulder bolts and stripper bolts, they can serve as shafts, axles, and guides for pulleys, gears, bearings, bushings, and other moving parts.

These screws were manufactured within tight tolerances for use in precision applications.
