S-90911A624 3/8"-16 x 1" ASME B18.9, SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 120,000 psi tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance through zinc plating, extending service life in harsh agricultural and industrial environments
• Positive anti-rotation locking with square neck design that prevents bolt turning during installation and operation
• Enhanced durability with Rockwell C25 hardness rating that maintains structural integrity under repeated stress
• Optimized thread engagement through UNC coarse threading that provides faster assembly and better performance in dirty conditions
• Secure flush mounting with standard 82° flat head profile that sits perfectly countersunk for smooth surface applications
• Reliable mechanical properties backed by Grade 5 classification ensuring consistent performance across all fasteners

Professional Applications & Engineering Value

These Grade 5 plow bolts are engineered to solve critical fastening challenges in demanding environments. The zinc-plated steel construction provides essential corrosion protection for agricultural equipment, snow plows, and industrial machinery exposed to moisture and chemicals. The square neck design addresses the common problem of bolt rotation during vibration, ensuring secure positioning without additional locking mechanisms. The 3/8"-16 UNC coarse threading offers superior performance in applications where debris accumulation is a concern, maintaining reliable thread engagement where fine threads might clog. With fully threaded construction and Class 2A thread fit, these bolts deliver consistent clamping force across the entire length, making them ideal for heavy-duty mounting applications requiring uniform pressure distribution.

Specification Summary & Compliance

These plow bolts feature precision 3/8"-16 UNC coarse threads with Class 2A fit for optimal assembly tolerance. Manufacturing complies with ASME B18.9 specifications SAE J429, ensuring dimensional accuracy and performance reliability. The fasteners are fully compliant with RoHS 3 (2015/863/EU) environmental standards and REACH (EC 1907/2006) regulations (06/14/2023 235 SVHC), meeting international requirements for hazardous substance restrictions and chemical safety.
