A clevis pin is a versatile, cylindrical, non-threaded fastener that comes in multiple designs to hold components securely between its head and end. These pins excel at rapid assembly or disassembly of equipment in both short-term and long-term setups, particularly where precise alignment isn't critical.

Clevis pins primarily function to prevent relative movement between two parts. They may also be referred to as clevis pin retaining clips, hinge pins, or link pins. While similar to bolts, clevis pins are distinguished by being either partially threaded or unthreaded and featuring a cross-hole for split pin insertion.
