S-90911A673 7/16"-14 x 1 1/2" ASME B18.9, SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel coating, extending service life in harsh outdoor and industrial environments.
• High-strength reliability with Grade 5 classification and 120,000 psi tensile strength, ensuring secure fastening under heavy loads.
• Optimized flush mounting thanks to the standard flat head with 82° countersink angle, preventing snagging and providing a smooth surface.
• Enhanced anti-rotation performance from the square neck design, which locks securely into mating parts to resist loosening under vibration.
• Easy installation and removal with fully threaded UNC coarse spacing, allowing for quick assembly and disassembly in field applications.
• Consistent dimensional accuracy with Class 2A thread fit, ensuring reliable interchangeability and reduced risk of cross-threading.
• Robust material hardness rated at Rockwell C25, providing excellent wear resistance and durability in demanding agricultural and industrial uses.

Professional Applications & Engineering Value

Engineered for heavy-duty applications, this Grade 5 plow bolt excels in environments where vibration, impact, and corrosion are common challenges. The zinc-plated steel construction offers a protective barrier against moisture and chemicals, making it ideal for agricultural equipment like plows, tillers, and snow removal attachments. The flat head with 82° countersink angle ensures a flush fit, reducing protrusions that could catch debris or cause injury. Combined with the square neck, it prevents rotation during torque application, maintaining clamp load in high-stress assemblies. The fully threaded UNC coarse thread design allows for deep engagement and rapid installation, saving time in maintenance and repair operations across construction, mining, and material handling sectors.
