Oversized Dowel Pins

These pins are slightly oversized to fit worn, enlarged holes where standard pins would be too loose. They’re typically used to replace dowel pins that no longer fit snugly.

Steel

High-Strength Alloy Steel—Our strongest, most wear-resistant pins, these won't bend or break from vibration. Use them for high-stress applications, such as mounting and aligning hydraulic cylinders and injection molds. They perform best in dry environments since moisture will cause them to rust.

Corrosion-Resistant Stainless Steel

18-8 Stainless Steel—The choice for wet and outdoor environments. In addition to resisting rust, these pins also withstand mild chemicals such as cleaners and degreasers. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

Oversized Ejector Pins

To fit in holes that have widened from wear and are too big for standard ejector pins, these pins are oversized. Also known as knockout and forged pins, they’re used to push parts out of molds. These pins are H13 tool steel, so they resist rapid changes in temperature. They’re hardened for strength and wear resistance and precision ground to tight tolerances. Machining is not recommended.
