Shoulder Bolt

What is a Shoulder Bolt?

A shoulder bolt, also known as a shoulder screw or stripper bolt, is a type of fastener that features a smooth, unthreaded cylindrical section called the shoulder between the head and the threaded portion. This shoulder allows precise rotation or sliding of attached parts, making it ideal for applications requiring alignment, pivoting, or smooth movement. Shoulder bolts often come with a hex socket or slotted head for easy installation.

Key Features of a Shoulder Bolt:

Distinct Shoulder Design: Smooth, unthreaded section providing a bearing surface for moving parts.
Versatile Head Options: Available with socket (Allen) or slotted heads for secure fastening.
Material Options: Made from stainless steel, alloy steel, or brass for durability and corrosion resistance.
High Precision: Tight manufacturing tolerances ensure accurate fit and alignment.
Variety of Sizes: Offered in multiple shoulder diameters and lengths.

Common Uses:

Rotating and pivoting applications such as pulleys, linkages, and moving assemblies.
Tooling, jigs, and fixtures where precise alignment is required.
Electronics and automotive parts needing smooth bearing surfaces.
Furniture and equipment assembly for pivoting or detachable joints.
