Align parts and bolt them together using the same hole. Install the pin and then insert a bolt or screw through the center. You can also use these pins to route wires and tubing without the need to drill a separate hole. Hollow pins are lighter than solid pins, so they’re a good choice if you need to reduce weight in your assembly.

Steel

Low-Carbon Steel—These pins won't deform from stress and vibration. They're stronger than stainless steel but not quite as strong as alloy steel. Pins perform best in dry environments since moisture will cause them to rust.

Ejector Sleeves

Use these sleeves with mold pins to form holes, bosses, and other features in parts, and then push the parts out of the mold. Made from H13 tool steel, these sleeves are strong, hard, and resist wear. They've been surface hardened with a process called nitriding, which adds even more strength and wear resistance. They’re precision ground to tight tolerances. Machining is not recommended.
