Socket Shoulder Screws

Self colour socket shoulder screws. ISO 7379 (BS4168) & BSF BSW & UNC socket shoulder screws. These screws are available in metric and imperial sizes. Shoulder screws are sometimes known as stripper bolts.

A shoulder screw has a partially smooth shaft that will allow the bolted material some rotation and movement around the screw axis, while the threaded end will typically have a nut to maintain the screw's position. They are used in instances where pre-tapped holes require alignment with some tolerance. This allows the work pieces either a joint, pivot, or sliding motion.
