Shoulder screws, also known as shoulder bolts or stripper bolts, are fasteners that have a cylindrical shoulder between the head and threads. The shoulder acts as a fulcrum, allowing the screw to rotate without affecting the attached object’s position. These types of screws are often used in applications where precise spacing and alignment are critical, such as in machinery and electronic equipment.

Shoulder screws or bolts come in a variety of types, depending on the specific application requirements. Here are some common types: plain shoulder screws, knurled shoulder screws, slotted shoulder screws, hex socket shoulder screws, precision shoulder screws and shoulder bolt with locking element.
