Product Description

Shoulder screws, sometimes referred to as shoulder bolts or stripper bolts, get their name from the unique cylindrical shoulder found between the head and the threads of the screw. At Lyn-Tron, we manufacture precision shoulder screws, which are so named for the high tolerance (+/-0.0005) the shoulder diameter is held to. The round shape provide a nice finished look. Steel is inexpensive, easy to achieve finer surface quality requirements and provides relatively high strength properties. Multiple plating options are available to increase the material's corrosion resistance and alter its appearance.
