Shoulder screws are often supplied to ISO and DIN Standards, such as ISO 7379, DIN 609, DIN 610 and DIN 923. They can have hexagon socket drives, Torx drives and slotted drives.

What is a Shoulder Screw?

Shoulder screws are also known as shoulder bolts and stripper bolts. They have an accurately machined shoulder (shank) portion that is used for location or as a bearing surface. The standard tolerance on the shoulder element is f9 (for metric sizes), but generally they are slightly undersized with a +0, -0,025mm. The thread of the shoulder screw is smaller than the diameter of the shoulder itself. There are three main sections of a shoulder screw: shoulder, thread and head. In general they are specified by the diameter and length of the precision shoulder section.
When the shoulder screw is installed the unthreaded shoulder acts as an accurate location diameter for two parts and can also be used as a bearing surface, a guide for rolling parts and pivot points for pulleys and gears.
