5/64 x 1 5/8 Tension Pin (Slotted Spring Pin) is formed oversize before installation so the slotted body can compress as it is driven. The catalog term is tension pin, while many drawings use slotted spring pin and many shops say roll pin. Compared with a dowel-pin fit, the tension pin is usually chosen when economical retention matters more than tenths-level location.

Common uses include lever assemblies, actuator links, and retaining collars, where the pin retains parts without a threaded fastener. 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.
