Dowel Pins

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.

Corrosion-Resistant Stainless Steel

High-Strength Machinable 416 Stainless Steel—These pins hold their shape under stress and friction from moving parts. In addition to being the strongest stainless steel alloy, 416 is also the most machinable, so you can shape these pins to fit your hole. However, they are the least corrosion-resistant stainless steel option.
