Spring Tension Pins S/COL

Spring tension pins, often referred to as roll pins or slotted pins, are an essential component for any engineer or mechanic looking for a reliable, friction-fit fastener. These self-colour pins are crafted from high-quality spring steel, providing the necessary radial force to lock securely into a pre-drilled hole without the need for additional nuts or bolts. Because they are "self-colour," they retain their natural, unplated finish, making them ideal for applications where you might need to weld them or where they will be submerged in oil, preventing any plating from interfering with the bond or contaminating the fluid.

Whether you are working on a vintage restoration or maintaining heavy industrial machinery, our range covers both metric and imperial sizes. From delicate 1/16" pins for precision work to robust M5 options for larger assemblies, these pins are designed to withstand vibration and shear forces with ease. Their hollow design makes them lightweight yet incredibly strong, acting as a versatile alternative to solid dowel pins or cotter pins in many mechanical setups.

By choosing our self-colour spring tension pins, you are getting trade-quality components backed by our commitment to fast UK delivery and competitive pricing.
