Shoulder Bolts

What is shoulder bolts?

Shoulder bolts, also known as stripper bolts or shoulder screws, are fasteners with a cylindrical shank that features a larger diameter at one end, called the shoulder, and a smaller diameter at the other end. The shoulder of the bolt provides a precise and stable point of contact for the mating component, while the smaller diameter portion of the bolt is threaded to accept a nut or other fastening hardware.

Shoulder bolts are commonly used in applications where precise spacing or alignment is required, such as in machinery, electronic equipment, and robotics. They are also used in applications where a load must be transferred between two components, but some degree of disassembly or adjustment may be necessary, such as in the case of jigs, fixtures, and tooling.

Shoulder bolts can be made from a variety of materials, including steel, stainless steel, brass, and aluminum. They are available in a range of sizes, thread pitches, and shoulder lengths to accommodate different applications.

The specifications of shoulder bolts can vary depending on the manufacturer, but some common characteristics include:

1. Material: Shoulder bolts can be made from a variety of materials such as steel, stainless steel, brass, or aluminum. The material used will depend on the application and the desired properties of the bolt.

2. Thread: Shoulder bolts have a threaded portion that can vary in size and pitch. The thread size and pitch will determine the size and type of nut that can be used with the bolt.

3. Shoulder Diameter: The diameter of the shoulder can vary depending on the size of the bolt. This diameter will determine the size of the hole that the shoulder will fit into.

4. Shoulder Length: The length of the shoulder can also vary depending on the size of the bolt. The length of the shoulder will determine the distance between the mating components.

5. Head Style: Shoulder bolts can have a variety of head styles, including hex, socket, and slotted. The head style will determine the type of tool required for installation and removal of the bolt.

6. Tolerance: Shoulder bolts can have different levels of tolerance depending on the application. Tighter tolerances may be required in applications where precise spacing or alignment is necessary.

It is important to consult the manufacturer's specifications when selecting a shoulder bolt for a specific application to ensure that it meets the required standards and will perform as expected.
