• Secure Anti-Rotation Fastening: The key locking neck design prevents the bolt from spinning during operation, offering a more stable and reliable connection that minimizes maintenance needs.
• Optimized for Easy Installation: Coarse UNC threads and a Class 2A thread fit allow for quicker assembly and disassembly, saving valuable time in field service and equipment upkeep.
• Robust Material and Construction: Made from high-strength steel with a standard flat head profile, this bolt delivers long-lasting service life and consistent performance in industrial settings.
• Compliance with Industry Standards: Meets SAE J429 specifications, ensuring consistent quality and interchangeability for plow and heavy machinery applications.
• Environmentally Responsible Manufacturing: RoHS 3 and REACH compliance guarantees the bolt is free from hazardous substances, supporting safer workplace and regulatory adherence.

Professional Applications & Engineering Value

This Grade 8 Plow Bolt is engineered to address critical challenges in heavy-duty industrial and agricultural equipment, such as snow plows, earth-moving machinery, and construction attachments. The key locking neck is a standout feature, designed to prevent rotation in high-vibration environments, which is a common failure point in standard bolts. This ensures that fasteners remain securely in place, reducing downtime and maintenance costs. The combination of 150,000 psi tensile strength and Rockwell C33 hardness provides exceptional resistance to shear and impact forces, making it ideal for applications where reliability is non-negotiable. The 3/4"-10 UNC coarse thread and partial threading allow for efficient installation in thick materials, while the flat head sits flush to avoid interference. By meeting SAE J429 standards, this bolt offers consistent performance and compatibility, ensuring it can be trusted for replacement or OEM use in demanding scenarios.
