3/16 x 3/16 Tension Pin (Slotted Spring Pin) is a spring steel roll pin for economical retention in a drilled hole. In search and purchasing records, this part may be called a tension pin, slotted spring pin, or 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.

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.
