Shoulder screws, also known as shoulder bolts, are a type of fastener. They consist of a cylindrical body with a shoulder or collar between the head and the threaded portion. The shoulder has a larger diameter than the threaded portion and is a precise reference point or bearing surface.

The shoulder diameter is ground to a closer tolerance than ordinary stripper bolts. This tighter tolerance ensures better-bearing action, allowing for smoother rotation and improved performance.
Car lane Mfg. offers both inch and metric shoulder screws available in thread diameters from 1/4" to 3/4" (8 to 20mm). Precision shoulder screws are a reliable choice for high-performance and critical applications. This is due to their close tolerance, plus tolerance shoulder length and DFARS compliance.
