7/32 x 9/16 Tension Pin (Slotted Spring Pin) is intended for driven installation where the slot closes as the pin enters the hole. Tension pin, slotted spring pin, and roll pin describe the same slotted self-retaining pin style. As the pin enters the hole, the slotted wall compresses and the spring steel reacts outward against the hole surface.

For simple joints replacing taper pins, retaining stops, or service fixtures, check the drilled-hole range, pin length, and access for driving the pin squarely. For worn precision holes, 0.001 Oversize Dowel Pins may be the better repair path than using a spring pin.

Cold Headers has supplied specialty fasteners since 1962 and helps buyers confirm exact pin sizes for maintenance or production requirements. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
