S-90934A931 3/4"-10 x 2 1/4" SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional load-bearing capability with Grade 8 classification and 150,000 psi tensile strength for reliable performance in high-stress environments
• Superior corrosion resistance provided by zinc yellow-chromate plating on steel, extending service life in outdoor and harsh conditions
• Secure anti-rotation locking through the square neck design that prevents bolt spinning during installation and operation
• Optimized thread engagement with UNC coarse threading and Class 2A fit ensuring easy installation and vibration resistance
• Enhanced durability with Rockwell C33 hardness maintaining structural integrity under repetitive impact and heavy loads
• Industry-standard compliance meeting SAE J429 specifications for consistent quality and interchangeability in plow equipment
• Versatile oval head profile with 82° countersink angle providing flush mounting and improved aerodynamics in moving applications

Professional Applications & Engineering Value

These Grade 8 plow bolts deliver critical engineering solutions for heavy-duty applications where failure is not an option. The zinc yellow-chromate plated steel construction combats corrosion in agricultural, construction, and snow removal equipment exposed to moisture and chemicals. The square neck design mechanically locks the bolt against rotation, eliminating the need for secondary locking mechanisms during plow blade adjustments. With UNC coarse threading and Class 2A thread fit, installation is streamlined while maintaining secure fastening under extreme vibration. The 150,000 psi tensile strength and Rockwell C33 hardness ensure these bolts withstand the impact loads and abrasive conditions typical in ground-engaging equipment, reducing maintenance downtime and replacement costs.

Specification Summary & Compliance

These plow bolts feature precision 3/4"-10 UNC coarse threading with Class 2A thread fit for consistent engagement and interchangeability. Manufacturing complies with SAE J429 specifications for Grade 8 fasteners, ensuring dimensional accuracy and mechanical properties. The 82° countersink angle and standard oval head profile provide proper seating in mating components. Materials and plating processes meet industrial standards for heavy-duty applications in construction and agricultural equipment.
