S-90911A632 3/8"-16 x 2" ASME B18.9, SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional Load-Bearing Capacity: With 120,000 psi tensile strength and Grade 5 classification, these bolts reliably handle high-stress applications without failure.
• Superior Anti-Rotation Performance: The square neck design locks securely into mating parts, preventing loosening under vibration and dynamic loads.
• Enhanced Corrosion Resistance: Zinc-plated steel construction provides durable protection against rust and environmental degradation in harsh operating conditions.
• Optimized Thread Engagement: Coarse 3/8"-16 UNC threads with Class 2A fit ensure quick installation and reliable fastening in various materials.
• Industry-Standard Compatibility: Flat head with 82° countersink angle and standard plow bolt profile ensures perfect fit with existing equipment and replacement parts.
• Consistent Mechanical Performance: Rockwell C25 hardness maintains structural integrity and prevents deformation under heavy mechanical loads.
• Full Thread Accessibility: Completely threaded shaft allows for flexible positioning and maximum grip length in diverse assembly scenarios.

Professional Applications & Engineering Value

These Grade 5 plow bolts deliver critical engineering solutions for heavy equipment and agricultural machinery where vibration resistance and structural integrity are paramount. The zinc-plated steel construction combats corrosion in outdoor and high-moisture environments, while the square neck design provides positive locking that eliminates rotation during equipment operation. The coarse UNC threading ensures reliable fastening in softer materials and worn holes common in plow blades, construction attachments, and earth-moving equipment. With 120,000 psi tensile strength, these industrial fasteners maintain bolt preload under extreme dynamic loads, preventing joint failure in critical applications. The flat head profile with standard countersink creates flush surfaces that prevent material buildup and reduce wear points.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit and 3/8"-16 UNC coarse thread specifications. These plow bolts conform to ASME B18.9 mechanical standards and SAE J429 Grade 5 requirements for consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety. The 82° countersink angle and standard flat head profile maintain interchangeability with existing industrial equipment configurations.
