S-91589A847 3/4"-10 x 3" SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional Strength & Durability: Grade 8 classification and 150,000 psi tensile strength ensure reliable performance under extreme loads and in demanding industrial environments.
• Superior Wear Resistance: Rockwell C33 hardness provides excellent resistance to abrasion and deformation, extending the bolt's service life in high-stress applications.
• Secure Anti-Rotation Locking: The key locking neck design prevents the bolt from turning during operation, ensuring a stable and secure fastening in vibrating machinery.
• Optimized for Heavy-Duty Applications: The coarse UNC threading and partial threading design allow for faster installation and superior grip in tough materials like those used in construction and agriculture.
• Guaranteed Material & Environmental Compliance: Manufactured from high-quality steel and compliant with SAE J429, RoHS 3, and REACH standards, ensuring material reliability and environmental safety.
• Precision Engineered Fit: Class 2A thread fit guarantees consistent and accurate mating with nuts, reducing the risk of cross-threading and assembly errors.
• Versatile Flat Head Design: The standard flat head profile with a 60° countersink angle allows for a flush finish, ideal for applications where a protruding head is not desirable.

Professional Applications & Engineering Value

This Grade 8 Plow Bolt is engineered to solve critical challenges in heavy machinery and equipment. Its high-strength steel construction and 150,000 psi tensile strength make it ideal for withstanding the intense shock and vibration encountered in agricultural plows, construction equipment, and industrial machinery. The key locking neck is a vital feature that prevents rotation, a common failure point in dynamic systems, ensuring operational integrity. The coarse UNC threading and partial threading provide excellent holding power in abrasive or coarse materials, reducing the risk of stripping and enabling quicker assembly. By combining robust material properties with a specialized flat head design, this bolt delivers long-term reliability and reduces maintenance downtime in the most demanding professional applications.
