1/8 x 15/16 Tension Pin (Slotted Spring Pin) is built around the slotted spring-pin principle: free diameter larger than the recommended hole. The slotted construction is the reason this same fastener is commonly indexed as a spring pin or roll pin. The slot accommodates the difference between the 0.131-0.135 in. free OD and the smaller 0.125-0.129 in. hole.

For lever assemblies, actuator links, or retaining collars, check the drilled-hole range, pin length, and access for driving the pin squarely. If the joint must locate parts precisely rather than retain them economically, a dowel pin is usually the product family to check.

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.
