S-90911A724 1/2"-13 x 3" 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 for reliable performance in high-stress environments
• Superior corrosion resistance through zinc-plated steel construction, extending service life in outdoor and harsh conditions
• Secure anti-rotation locking provided by the square neck design, preventing bolt turning during installation and operation
• Optimized thread engagement with UNC coarse spacing and Class 2A thread fit ensuring quick assembly and vibration resistance
• Flush mounting capability with standard 82° flat head profile for smooth surface finishes in agricultural and construction equipment
• Enhanced durability from Rockwell C25 hardness, maintaining structural integrity under repetitive impact and heavy loads
• Full-length threading versatility allowing flexible positioning and secure fastening across the entire 3" length

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these Grade 5 plow bolts deliver critical performance where failure isn't an option. The zinc-plated steel construction provides essential corrosion protection for agricultural equipment, snowplow assemblies, and construction machinery exposed to moisture and abrasive materials. The square neck design solves common rotation issues during torque application, while the UNC coarse threads enable rapid installation in field maintenance scenarios. With fully threaded right-hand configuration and 82° countersink, these bolts ensure flush mounting that prevents material buildup on surfaces - a crucial advantage for plow blades and material handling equipment where smooth surfaces reduce drag and wear.

Specification Summary & Compliance
