WHAT IS A SPRINGPIN AND WHY USE IT?

WHAT IT IS:

The Springpin is a slotted or coiled cylindrical fastener, heat-treated or work hardened to achieve optimum toughness, resilience and shear strength. In manufacture, it is formed to a controlled diameter greater than the hole into which it is pressed. Springpins are stronger than mild carbon steel straight pins, taper pins or grooved pins of equivalent sizes.

WHAT IT DOES:

Compressed as it is driven into a hole, the Springpin exerts continuous spring pressure against the sides of the hole, positively preventing loosening by vibration. Springpin dimensions, outside diameters in their free state and elastic limits are engineered so that this self-locking action is achieved in holes drilled to normal production tolerances. No reaming operations are needed to assure a tight fit. No secondary operations are required to keep Springpins in position.

SAVES COST: The self-locking Springpin itself costs less than most tapered, notched, grooved or serrated pins. The installed cost is far less than fasteners requiring auxiliary locking means.

SAVES WEIGHT: Being hollow, the Springpin is lighter than a solid pin. Because it is self-locking, it saves the weight of projecting heads, tabs, and extra locking parts.

SAVES MAINTENANCE: Since the Springpin stays in place, it improves product reliability, cuts maintenance cost. Because the Springpin conforms to the drilled hole in which it is inserted and is not a splined or notched type pin, there is little wear on the hole; it is not necessary to re-drill and use a larger size pin.

SAVES TROUBLE: "Easy does it" at every step with the Springpin. Easily inserted - by hand or machine; readily removed for field servicing; easily replaced.

SAVES REJECTS: Since the Springpin is self-locking in an ordinary drilled hole, it eliminates the rejections and waste associated with close tolerances.

SAVES TIME: The Springpin not only saves time at each operation - it eliminates some operations altogether and in many instances permits a reduction in number of parts to be assembled.
