S-90911A732 1/2"-13 x 4" ASME B18.9, SAE J429 Plow Bolts

Key Features & Benefits at a Glance

• Exceptional tensile strength of 120,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Zinc-plated steel construction provides superior corrosion resistance, extending service life in harsh outdoor or industrial environments.
• Square neck design prevents rotation during installation, ensuring secure placement and saving time on assembly lines.
• Fully threaded 4" length offers maximum grip and adjustability, accommodating various material thicknesses with consistent holding power.
• Class 2A thread fit with UNC coarse threading allows for easier, faster assembly while maintaining strong engagement in tough materials.
• Grade 5 classification and Rockwell C25 hardness deliver optimal balance of strength and ductility for demanding mechanical applications.
• Compliance with ASME B18.9, RoHS, and REACH guarantees adherence to industry standards and environmental regulations for global procurement.

Professional Applications & Engineering Value

Engineered for heavy-duty applications, these plow bolts excel in agricultural equipment, construction machinery, and industrial assemblies where vibration resistance and structural integrity are critical. The flat head with 82° countersink angle sits flush with surfaces, minimizing protrusion in moving parts. The zinc-plated steel material combats rust in moisture-prone environments, while the square neck locks securely into place, eliminating spin-out during torque application. With fully threaded UNC coarse threads, installation is streamlined even in hardened materials, reducing labor time and ensuring consistent clamp load distribution across the 4" length. This combination of Grade 5 strength and precision engineering addresses common failures in dynamic load scenarios, providing long-term reliability for OEM and MRO needs.
