Vibration-Resistant Slotted Spring Pins


End View
Interlocking teeth help these pins resist sliding when exposed to vibration. Also known as roll, tension, split, and expansion pins, they have a slot that presses closed when the pins are inserted so they don't flex after installation. Use them for fastening, pivoting, and holding.
Squeeze pins closed and install them in a hole. Tension holds them tight against the hole wall. The ends are chamfered to aid insertion.
Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Pins are made of vanadium steel for excellent wear resistance.
