2. What are the key features of a shoulder screw?

• Answer: Key features include:

• Non-Threaded Shoulder: The distinctive feature that provides a stable base.

• Threaded Portion: The threaded section that engages with a nut or a threaded hole.

• Head Styles: Various head styles, such as round, hex, and pan heads, for different installation methods.

• Materials: Typically made from metals like steel, stainless steel, brass, and aluminum.

• Sizes: Available in a range of sizes to fit different application requirements.

3. What are the typical uses of shoulder screws?

• Answer: Common uses include:

• Mechanical Fastening: Mounting bearings, bushings, and other components.

• Electrical Applications: Securing components in electrical enclosures and panels.

• Instrumentation: Mounting instruments and sensors.

• Automotive Industry: Used in various automotive components.

• Furniture and Woodworking: Hidden fastenings in furniture and woodworking projects.

4. What are the benefits of using shoulder screws?

• Answer: Benefits include:

• Stable Base: The non-threaded shoulder provides a stable platform for components.
