1/16 x 7/16 Tension Pin (Slotted Spring Pin) is also known as a slotted spring pin or roll pin in engineering and shop-floor terminology. The catalog term is tension pin, while many drawings use slotted spring pin and many shops say roll pin. The pin OD is intentionally larger than the recommended hole before insertion, and the slot gives the diameter somewhere to close during driving.

Common uses include agricultural equipment linkages, outdoor mechanisms, and repair assemblies, where the pin retains parts without a threaded fastener. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin.

Since 1962, Cold Headers has helped industrial buyers locate specialty pin and socket-product configurations. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
