    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.

    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.

    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.
    Highly Corrosion-Resistant 316 Stainless Steel—Our most corrosion-resistant pins, these hold up in just about any environment. They won't degrade from exposure to weather, salt water, and most chemicals. Like 18-8 stainless steel, they're strong enough to join most components but won't withstand stress and vibration as well as 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.
    Material Certificate—Pins include a report with a traceable lot number and a description of their chemical, physical, and mechanical properties.

    The best spring pins for joining parts exposed to vibration and shock. They're often used in power transmission, automation, and other assemblies with constant motion and sudden starts and stops. Because of their spiral shape, they flex to conform to holes that aren’t perfectly round.
    Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.
    Wear-Resistant 400 Series Stainless Steel—Our most wear-resistant stainless steel pins, these are good for pivoting parts that create a lot of friction. They hold up in environments that experience occasional moisture, but they're not as corrosion resistant as 18-8 and 316 stainless steel.

    Shoulder-Style Ejector Pins

    A thick shoulder underneath the head makes these pins more rigid than standard ejector pins. Also known as knockout and forged pins, use them to push parts out of molds. They're precision-ground to tight tolerances and hardened for strength and wear resistance. Machining is not recommended.
    Pins are made of H13 tool steel to resist rapid changes in temperature.
