5 Uses for Clevis Pins in Sailing Boats

Philadelphia, Pennsylvania – Many industrial fasteners are used in various applications, whether for construction, aeronautics, electronics, agriculture or transport. In sailboats, for example, clevis pins are used as versatile fasteners for connecting lines, holding parts together, and for other fastening purposes.

Clevis pins are paired with a two-pin U-shaped fastener called a clevis. When used together, the metal pin is inserted through the holes on the clevis teeth. Then the clevis pin is fixed at the end by inserting a cotter pin or cotter pin through the hole. All of these fasteners are usually made from stainless steel, although they can also be made from other materials. They are also available in different models, finishes and sizes, which you can select using a easy reference chart on line.

Clevis ties can support heavy loads and are frequently used to secure cargo. They are also ideal for sailboats as they allow movement while keeping things in place. With this ability, clevis ties can withstand high winds, sudden movements, and continuous vibration from the boat’s engine.

Although clevis pins can be small, they play a vital role in keeping a boat strong, secure and functional. Here are some of the ways clevis pins are used in sailboats:

1. Clevis pins connect anchor line components

The belay line is made up of three elements: the anchor, the rope and the metal chain. Clevis pins and ties connect these components, forming a complete anchor line.

First, the rope is connected to the chain, then the chain is attached to the anchor for added weight and strength. Clevis pins and ties are ideal for connecting the three components of the anchor line due to their durability, flexibility and resistance to moisture.

In addition to these features, it is also easy to place, adjust and remove clevis clips, making them ideal for sailboat.

2. Clevis pins connect the forestay to the mast

The forestay is a standing rigging that supports the mast of a sailboat. This line is usually made of stainless steel wire. It goes from the bow of the boat to the end of the mast. The mast and forestay should be securely fastened to withstand strong winds and other sources of movement and pressure. Therefore, clevis pins and fasteners are used to connect them.

In addition to supporting the mast, the forestay can also have staysails attached. The staysails improve the sail power of a boat, therefore the stays must be durable and firmly fixed with clevis pins.

3. Clevis pins can connect the rudder to the sternpost

The rudder of the boat is a steering element located behind the propeller. Its main purpose is to deflect the flow of water and keep the boat upright while being maneuvered. The rudder usually has a flat, smooth surface and is made of wood or metal.

The rudder is attached to the stern of the boat using clevis pins and nuts. These fixing materials make it possible to operate the rudder using a steering wheel and a cable.

4. Clevis pins can be used as door hinges

The flexibility of the clevis pins and the U-shaped clevis allow them to be used as door hinges, and they can be used as such for sailboat hatches. The clevis and pins are attached to the door frame and the door, securing one side while allowing movement on the other.

They are ideal for this purpose as they are durable, flexible and easy to remove and replace if necessary.

5. Clevis pins secure the keel to the hull

The keel is a necessary attachment for sailboats because it keeps the watercraft upright and stable. The fin-like part commonly found in the middle of the hull is made of heavy metal and functions as the balancing element of the boat.

Some boats have keels built into the hulls. Meanwhile, some are designed as separate parts and therefore need to be attached to the bottom of the watercraft. They can also be maneuvered depending on the direction the boat is pointing.

For the latter type, clevis pins and clips can secure the keel wire to the hull. The line will then support the keel when it is lowered or raised.


The clevis pin and attachment are very useful for attaching and securing various parts and accessories of a sailboat. It supports functionality, flexibility and durability while allowing for easy adjustment. Although they may seem small and simple, clevis pins can be considered essential boating items that you will need for a safe and enjoyable boating experience.
