1/2 x 1 3/4 Tension Pin (Slotted Spring Pin) is also known as a slotted spring pin or roll pin in engineering and shop-floor terminology. 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.
This size is often reviewed for sheet metal stacks, alignment-plus-retention work, and panel assemblies 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 supports hard-to-find pin sourcing, including uncommon lengths and exact diameter-length combinations. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
