Shoulder Screws with Slotted Pan Head DIN 923 in A1 Stainless Steel

Shoulder bolts with a slotted pan head. Also know as stripper bolts, this type of machine screw has a wider diameter shank than the diameter of the threaded part. This change in diameter creates a shoulder against which the bolt is tightened, making them ideal as shafts for rotating bushings and bearings. They are also used to align components in assemblies, as pivots, guides, pins, linkages and trunnion mountings. The main dimensions for shoulder bolts refer to the shoulder of the screw rather than the thread, with the length measured from under the head to the end of the shoulder. Shoulder screws also include an undercut between the thread and shoulder, to allow a close fit.
