Frequently Asked Questions About Clevis Pins

What size clevis pin do I need?

Start by measuring the hole diameter in your clevis bracket. Most farm and trailer applications call for a pin between 3/8 in. and 1/2 in. in diameter, though brackets vary widely. An undersized pin won't fit correctly and can shift under load.

What is the difference between a clevis pin and a cotter pin?

A clevis pin is the primary connector that joins two components by passing through the clevis bracket. A cotter pin or wire lock is the retention fastener that goes through a hole near the pin's end to hold it from backing out. They serve different functions and are typically used together.

Clevis Pins

A clevis pin does a sole job: it passes through a bracket to lock two components together and keep them there under load. Tractor Supply stocks these specialized types of pins in multiple diameters and locking styles for farm equipment, trailer hitches and chain-rigging hardware.

Load-Ready Fasteners for High-Stress Jobs

Clevis pins work by passing through the paired holes of a U-shaped bracket to connect two components and hold them in alignment. A clip or locking wire then threads through a small hole near the pin's tip, keeping it from working loose under movement or vibration. Securing hardware in demanding setups calls for a material that holds up under repeated stress, which is why most clevis pins are built from steel. Steel resists bending under tension and holds its shape at the contact points over time, making it the standard choice for tractor drawbars, trailer tongues and chain-rigging applications.

Pin Styles for Multiple Connection Sizes

Brackets and hitches don't all share the same dimensions, so a pin that can adjust to the connection saves time on the job. Adjustable clevis pins have multiple holes along the shank, and the retaining clip seats in whichever hole best matches the bracket thickness. Universal clevis pins take a different approach, machined to fit a broader range of clevis brackets without any repositioning. To ensure you have the right clevis pin available, assorted sets provide a mix of commonly used sizes.

Heavy-Duty Clips for High-Load Connections

High-load connections, such as those on large tractor attachments and heavy trailer tongues, put more stress on a joint than a basic adjustable pin is rated to handle. Straight clevis pins paired with a locking clip are built for those applications, with heavy-duty models carrying working load limits suitable for farm use. The clip passes through a hole at the pin's end and locks the pin in position against vibration and side load. That kind of rated, locked connection is what keeps heavy equipment running safely through a full day of Life Out Here.

Stock Up on Clevis Pins from Tractor Supply

Clevis pins carry the load at some of the most stressed connection points on a piece of farm equipment. Matching the right diameter and locking style to the bracket keeps the joint tight and extends the life of the surrounding hardware.
