Shoulder Bolts
Shoulder Bolts for Precise and Durable Alignment
Shoulder bolts, also known as shoulder screws or stripper bolts, are sturdy threaded fasteners that feature a threaded end, a a smooth, unthreaded shoulder (typically featuring a larger diameter than the threaded portion), and a circular head that is either knurled or smooth and shaped with either a cap, hex, flat, low, or ultra-low profile. These bolts are often used in applications that require tight tolerances, like those in the aerospace or automotive industry (among others); the smooth shank is often used as a spacer, pivot point, guide, or fulcrum.

What to Consider When Selecting a Shoulder Bolt
Size and tolerances are always an important factor to consider when selecting shoulder bolts to ensure the alignment is correct.
The surface finish is also key – not only will this affect the bolt’s corrosion resistance, but the texture of the shaft surface may impact the performance of mating components.
Finally, consider the head style and how its drive matches the available tools and how its shape will fit within the application space.
