S-90934A808 5/8"-11 x 3 1/2" SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional strength for demanding applications with Grade 8 classification and 150,000 psi tensile strength, ensuring reliable performance under extreme loads.
• Superior corrosion resistance provided by the zinc yellow-chromate plating on steel, extending the bolt's service life in harsh outdoor and industrial environments.
• Maximum anti-rotation and secure fastening due to the integrated square neck design, which prevents the bolt from turning during installation and operation.
• Optimized for heavy-duty use featuring a Rockwell C33 hardness and coarse UNC threads for high resistance to wear, stripping, and vibration loosening.
• Precise and reliable threading with a Class 2A thread fit, ensuring easy assembly and a consistent, secure connection in compatible nuts and components.
• Versatile partial threading allowing for a non-threaded shank to bear shear loads effectively, making it ideal for dynamic applications like plow attachments.
• Industry-standard compliance meeting SAE J429 specifications, providing assurance of quality and interoperability in agricultural and industrial machinery.

Professional Applications & Engineering Value

This Grade 8 plow bolt is engineered to solve critical challenges in heavy-duty agricultural and industrial applications, such as snow plows, earth-moving equipment, and heavy machinery. The zinc yellow-chromate plated steel construction offers robust corrosion resistance, essential for equipment exposed to moisture, chemicals, and abrasive materials. The square neck design is a key feature that locks the bolt securely into place, preventing rotation and reducing maintenance downtime. Combined with coarse UNC threads and a partially threaded shank, it provides excellent grip and load distribution, minimizing the risk of joint failure under high stress and vibration. This makes it a reliable choice for OEMs and maintenance teams seeking durable, SAE J429 compliant fasteners that enhance equipment longevity and safety.
