Clevis Pin

A clevis pin is an important fastener. It’s used to hold parts together in machines where they need to pivot or connect along a straight line. It has a round shaft with a hole drilled in one end for a cotter pin or split ring. This keeps it from failing when there’s a lot of stress or heavy loads. The design is simple but tough, so it’s easy to put in and take out. That makes it a good choice for setups where you need to adjust things often.

You’ll see these pins a lot in linkages, control systems, and heavy machinery. They keep everything stable while letting parts rotate or move. They’re made to specific standards, so industries that need safe, long-lasting parts rely on them a lot.

They are used in linkages, control systems, and heavy machinery to allow connected parts to rotate or move, but operate stably and not get out of place. We manufacture our pins to quality standards and are often used in industries that require safe and durable parts.

Size

Clevis pin come in standard sizes: diameters from 1/4 inch to 2 inches and lengths from 0.5 inches to 12 inches. They follow norms like ASME B18.8.1 or ISO 2341. If you need custom sizes for special machines, they can be made with tight tolerances,even as small as ±0.001 inch. The hole through the pin (for the cotter pin or R-clip) is machined precisely so it lines up perfectly.

There are both metric and imperial versions, so they work anywhere in the world. Manufacturers give CAD models to help with engineering designs. For setups that vibrate a lot, there are options with knurled or grooved surfaces to keep the pin from slipping.

Common Materials and Durability

Our clevis pins are made of high-quality stainless steel or carbon steel. Carbon steel pins are heat treated to make them stronger and more wear-resistant. Stainless steel pins are not easy to rust, which is very suitable for harsh environments. For carbon steel pins, we will add zinc plating or other anti-rust layers to protect them.

We will carefully check each batch of pins to ensure that the hardness and size are consistent. This way, they can work stably and long-term in applications such as mechanical linkages, agricultural machinery or construction equipment. If you need a specific material suitable for your load or environment, please let us know and we can customize it for you.
