What is shoulder bolts

Shoulder bolts, also known as shoulder screws or stripper bolts, are a unique type of fastener that combines a few distinct features. These bolts consist of three main sections: a head, a shoulder, and a threaded portion. The shoulder section is an unthreaded cylindrical portion between the head and the threaded portion, which provides specific functionality in various applications.

Characteristics of Shoulder Bolts:

1. Three Main Sections: Shoulder bolts have a head, an unthreaded shoulder, and a threaded portion.

2. Shoulder Diameter: The diameter of the unthreaded shoulder is larger than the threaded portion, providing a smooth transition between components.

3. Head Types: Available in various head types including hex socket (Allen), slotted, Phillips, and others, allowing different tools for installation.

4. Materials: Made from various materials such as stainless steel, alloy steel, brass, and aluminum to suit different application requirements.

Applications of Shoulder Bolts:

1. Pivot Points: Used in pivoting and rotating applications where precise alignment and smooth movement are required.

2. Spacer or Standoff: Act as a spacer or standoff between two components, maintaining a precise gap or clearance.

3. Tool and Die Fixtures: Utilized in tool and die fixtures for precise alignment and spacing of components.

4. Manufacturing and Machinery: Found in machinery and manufacturing equipment where accurate positioning and alignment are crucial.

Advantages of Shoulder Bolts:

1. Precise Alignment: The unthreaded shoulder provides accurate alignment and smooth movement between components.

2. Strength and Stability: The shoulder’s larger diameter increases the bolt’s strength and stability.

3. Reduction of Wear: Helps reduce wear between mating parts by acting as a buffer between components.

Types of Shoulder Bolts:

1. Standard Shoulder Bolts: Featuring a cylindrical shoulder section with a standard diameter.

2. Precision Shoulder Bolts: Manufactured with tight tolerances, providing higher precision in terms of shoulder diameter and thread alignment.
