Customized Phillips head machine step screws

Shoulder/step Screws, also known as Shoulder Bolts, are used for several different applications,including those that

involve rotation or require a locking type of screws. Shoulder Screws are distinct from other types of screws due to

the fact that they are only partially threaded, leaving a smooth-sided round or square shaft between the threading

and the head. This shaft is usually slightly larger than the threaded portion of the screw. Often used in automotive and mechanical applications.
