Understanding Springs – Clips & Pins

Spring Clips

A spring clip is a small, flexible metal component designed to hold, secure, or position parts in an assembly. It uses the inherent elasticity of spring steel to apply constant pressure, ensuring a firm grip without the need for screws or bolts.

Key Features:

• Made from spring steel or stainless steel for durability.
• Designed to snap into place and maintain tension.
• Available in various shapes: U-clips, E-clips, C-clips, and custom designs.

Common Applications:

• Automotive panels and trim.
• Electrical connectors.
• Securing hoses or cables.

Spring Pins

A spring pin (also called a tension pin or roll pin) is a cylindrical fastener used to align or secure two components. It’s made by rolling spring steel into a hollow cylinder with a slit, allowing it to compress slightly during installation and expand to hold firmly in place.

Key Features:

• Self-retaining due to spring tension.
• Absorbs shock and vibration better than solid pins.
• Available in slotted or coiled designs.

Common Applications:

• Machinery assemblies.
• Automotive gear systems.
• Hinges and rotating joints.
