Hardware Shoulder Screws

Shoulder screws, also known as shoulder bolts or stripper bolts, are versatile fasteners used for spacing and bearing surfaces in various applications. Their design makes them ideal for pulleys, gears, rolling wheels, and other mechanical assemblies, as the shoulder sits above the hole, allowing connected parts to rotate freely. They can also be used with stripper plates for high-torque fastening in tight spaces.

Shoulder screws, also known as shoulder bolts or stripper bolts, are precision fasteners characterized by a cylindrical, unthreaded shoulder located between the head and the threaded portion. The shoulder’s diameter is slightly larger than that of the threads, providing a bearing surface that allows for rotation of connected components, making these screws ideal for applications like pulleys, gears, and rolling wheels. Commonly used in industries such as electronics, automotive, and machinery, shoulder screws offer reliable spacing, alignment, and fastening solutions.

Manufactured from materials like stainless steel, brass, and steel, they exhibit excellent durability and corrosion resistance. Standard sizes are available in both inch (e.g., 4-40, 6-32) and metric (e.g., M3, M4) dimensions, with shoulder diameters ranging from 1/8″ to 1/2″ or 3mm to 10mm. Custom dimensions can be produced upon request.
