Spring Dowel Pin

A Spring Dowel Pin, also known as a Slotted Spring Pin or Roll Pin, is a hollow cylindrical fastener with a longitudinal slot that allows it to compress during installation and expand after insertion. This self-retaining design provides a secure and vibration-resistant fit, making it ideal for locating, aligning, and fastening components in mechanical and industrial assemblies.

Manufactured from high-quality spring steel, stainless steel, or alloy steel, spring dowel pins offer excellent strength, elasticity, and durability. Their flexible construction enables them to absorb shock loads, compensate for hole tolerances, and maintain a firm grip even under dynamic operating conditions.

Spring dowel pins are widely used in automotive, machinery, aerospace, agricultural equipment, electrical devices, and engineering applications where precise alignment and reliable fastening are essential.
