S-90911A633 3/8"-16 x 2 1/4" 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 demanding applications
• Superior corrosion resistance through zinc-plated steel construction, extending service life in harsh environments
• Secure anti-rotation locking provided by square neck design that prevents bolt turning during installation and operation
• Optimized flush mounting with 82° countersink angle and flat head profile for smooth surface integration
• Enhanced thread engagement through fully threaded UNC coarse spacing design for faster assembly and superior holding power
• Consistent performance reliability with Rockwell C25 hardness maintaining structural integrity under repeated stress
• Broad compatibility with Class 2A thread fit ensuring proper mating with standard industrial components

Professional Applications & Engineering Value

These Grade 5 plow bolts deliver critical engineering solutions for heavy-duty equipment where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for agricultural machinery, snow removal equipment, and construction implements exposed to moisture and abrasive conditions. The square neck design effectively prevents rotational movement in high-vibration environments, eliminating the need for additional locking mechanisms. With fully threaded UNC coarse spacing and 82° countersink angle, these bolts offer rapid installation while maintaining flush surface profiles essential for moving parts and ground-engaging equipment. The combination of 120,000 psi tensile strength and Rockwell C25 hardness ensures these fasteners withstand extreme operational stresses without compromising performance.
