3/16 x 3 1/4 Tension Pin (Slotted Spring Pin) supports economical retention in hinges, pivots, and light mechanical joints. Use the three names together when cross-checking older maintenance notes, bills of material, or shop requests. A normal drilled hole at production tolerance is typically the economic advantage over precision reamed dowel-pin holes.

Common uses include cabinet mechanisms, access panels, and hinged service hardware, where the pin retains parts without a threaded fastener. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin.

For repair operations, distributors, and OEM sourcing, Cold Headers can help match the item number, diameter, length, and standard. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
