1/64" Dowel Pins | McMaster-Carr

Precisely align machine parts and prevent movement during assembly. These dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. They can also be used as a pivot, shaft, or hinge to join moving components. Since dowel pins can be hard to remove, they are best suited for permanent fixtures that don't require frequent adjustments or disassembly.

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.
