1/8 x 2 3/4 Tension Pin (Slotted Spring Pin) provides headless fastening for compact joints where a screw head or nut would interfere. Use the three names together when cross-checking older maintenance notes, bills of material, or shop requests. The chamfered ends support driving from either side, while the open slot allows compression during installation.

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.
