The threads of shoulder screws do not extend all the way from the top to the head, so they have a smooth shank at the bottom of the head. They are also sometimes called shoulder bolts and dump bolts. Shoulder screws reduce rotation by locking, in industrial applications v
very common. 

Shoulder screws can also have different types of heads, such as slotted, cross-recessed or hex heads. The length and diameter of the shoulder are often as important as the size of the threaded portion, since the smooth portion of the shaft is an important function of the bolt. Shoulder screws are made of stainless steel, which is nearly as strong as steel and will not rust in outdoor or washdown environments. 

Due to the special design of their shoulders, these shoulder screws can be used for many special purposes. For example, they are often used in automotive or mechanical applications because unthreaded shoulders are good fasteners for pulleys, linkages, and other moving parts. Also because shoulder screws provide smooth, accurate movement, they are often used where accuracy is important, such as measuring equipment, optical fixtures, and laboratory equipment.
