Shoulder bolts, or shoulder screws, have a long, unthreaded, cylindrical shoulder that is larger in diameter than the threads. Also known as stripper bolts.

They are a type of screw with three distinct sections: the head, the unthreaded shoulder, and the threads. These types of screws consist of integral threads that are present on half or less of the screw shank and the rest of the shaft is enlarged and smooth to allow the bolted material the ability to rotate or move around the screw axis.
