1/16 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 packaging equipment, changeover hardware, and machine covers when a self-retaining driven pin is specified. If the joint must locate parts precisely rather than retain them economically, a dowel pin is usually the product family to check.

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.
