RS PRO 2 mm Diameter Galvanised Steel Spring Pin

Slotted Spring Tension Pins consist of a single coil of spring steel with an open slot enabling the pin to reduce in diameter as it is driven into a hole of appropriate size. A tension pin allows you to securely fix various machine parts together acting as a fastener between the parts.

• Corrosion resistant zinc plated carbon steel.

You can add to the strength of the slotted tension pins by simply inserting a smaller diameter pin inside the outer / larger pin. You securely insert the larger pin first then insert the smaller diameter pin into the larger diameter pin. Always make sure that the slot of the smaller diameter pin is NOT in-line with the larger pin.

A spring pin is also known as a Roll Pin or a Tension Pin. The pin allows you to securely fix various parts of a machine together acting as a self-retaining fastener between the parts. The diameter of the pin is larger than the diameter of the hole it will be inserted into.
