Cotter Bolt

Updated: 2026-07-31

Overview

A clevis bolt is a specialized fastener designed for use with clevis pins, commonly found in mechanical and structural applications. It consists of a threaded shaft and a head, which may be flat or domed, and is often used to create adjustable connections. This type of bolt is essential in industries requiring reliable and secure fastening solutions, such as construction, automotive, and heavy machinery. Its versatility and strength make it a preferred choice for applications where stability and adjustability are critical.

Structure and Working Principle

The clevis bolt features a threaded shaft that allows it to be secured into a threaded hole or used with a nut. The head of the bolt is designed to fit into a clevis, a U-shaped connector, which is then secured with a clevis pin. This design enables the bolt to pivot within the clevis, providing flexibility in alignment and movement. The threaded portion ensures a tight and secure fit, preventing loosening under vibration or load.

Key Features

Clevis bolts are known for their durability and strength, often made from high-quality materials like carbon steel or stainless steel. These materials provide resistance to corrosion and wear, extending the bolt's lifespan in harsh environments. Another key feature is the variety of head styles available, including flat and domed heads, which cater to different installation requirements. The threaded shaft is precision-cut to ensure a secure fit, reducing the risk of failure under stress.

Application Areas

Clevis bolts are widely used in industries that require robust and adjustable fastening solutions. In construction, they are used to secure structural components and machinery. The automotive industry relies on them for suspension systems and other critical assemblies. They are also prevalent in agricultural equipment, aerospace, and marine applications, where their ability to withstand high loads and environmental stressors is invaluable.

Maintenance and Precautions

Regular inspection of clevis bolts is essential to ensure they remain secure and functional. Check for signs of wear, corrosion, or thread damage, and replace any compromised bolts immediately. When installing, use the correct torque specifications to avoid over-tightening, which can strip threads or weaken the bolt. Lubrication may be necessary in high-friction environments to prevent seizing and ensure smooth operation.

B2B Procurement Guide

When sourcing clevis bolts for industrial use, consider the material, size, and thread specifications to ensure compatibility with your application. Stainless steel bolts are ideal for corrosive environments, while carbon steel offers high strength for heavy-duty use. Work with reputable suppliers who provide certifications for material quality and manufacturing standards. Bulk purchasing may offer cost savings, but ensure storage conditions prevent rust or damage before use.
