3/16 x 3 Tension Pin (Slotted Spring Pin) is a spring steel slotted pin used where the pin must compress on entry and push back after seating. 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.
In fixture stops, temporary tooling, and production aids, the headless form keeps the joint compact after installation. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin.
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.
