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. Brass is corrosion resistant, nonmagnetic, and easily machinable. Base metal is yellow, but many plating options are available when different colors are required.
