Slotted Spring Pins
Also known as roll, tension, split, and expansion pins, these pins have a slot along one side that you squeeze closed to install them into unthreaded holes. Once installed, they expand slightly, creating outward tension that holds them tight against the hole wall. These pins absorb shock and vibration in your system, and keep parts from loosening. They are often used as hinge pins, or to hold springs and power transmission components in place.
Install these pins into a hole. They have at least one chamfered end, which means the end is angled to make insertion easier.
Breaking strength is measured as double shear, which is the amount of force required to break a pin into three pieces.
Steel pins are strong and wear resistant. Pins with a black-phosphate or zinc-plated finish have an outer layer to protect the steel underneath from rust.
Pins that meet MS16562 conform to military standards for material and dimensions.
