Shoulder bolts—also known as shoulder screws or stripper bolts—are precision mechanical fasteners characterized by a cylindrical, unthreaded shoulder between the head and the threaded portion of the shaft. Designed to provide accurate alignment and support for rotating or sliding parts, these bolts are commonly used in assemblies that require movement, pivoting, or precise spacing. The shoulder acts as a guide or bearing surface for components such as gears, pulleys, bushings, linkages, or rotating arms.
The shoulder diameter is larger than the threaded portion, and its length is machined to tight tolerances to ensure consistent fit and performance. This allows for free rotation or sliding motion of mounted parts without binding. The threaded portion is used solely for clamping the bolt into a tapped hole or securing it with a nut, while the shoulder is the functional part of the bolt.
Shoulder bolts are typically manufactured from high-strength materials such as stainless steel, alloy steel, or brass, and are available in various shoulder lengths and diameters to suit different application needs. They come with a hex socket head for easy installation using Allen (hex) keys, making them ideal for precision assembly in industries such as automotive, aerospace, robotics, electronics, die and mold making, and industrial machinery.
