1/4 x 3/4 Tension Pin (Slotted Spring Pin) provides headless fastening for compact joints where a screw head or nut would interfere. Use the three names together when cross-checking older maintenance notes, bills of material, or shop requests. As the pin enters the hole, the slotted wall compresses and the spring steel reacts outward against the hole surface.

In latch mechanisms, lock hardware, and service doors, the headless form keeps the joint compact after installation. For worn precision holes, 0.001 Oversize Dowel Pins may be the better repair path than using a spring pin.

Cold Headers brings long-running industrial fastener experience to tension-pin quoting, cross-checking, and size confirmation. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
