5/32 x 4 Tension Pin (Slotted Spring Pin) is a headless spring pin for production or repair work that does not require precision dowel location. The slotted construction is the reason this same fastener is commonly indexed as a spring pin or roll pin. A normal drilled hole at production tolerance is typically the economic advantage over precision reamed dowel-pin holes.

This size is often reviewed for electronics assemblies, appliance hardware, and light mechanical frames when a self-retaining driven pin is specified. For worn precision holes, 0.001 Oversize Dowel Pins may be the better repair path than using a spring pin.

Cold Headers can assist when drawings, service records, and replacement needs call for an exact spring pin size. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
