Professional Applications & Engineering Value

These Grade 8 plow bolts are engineered to address critical challenges in agricultural and industrial settings, where high stress and corrosive conditions are common. The zinc yellow-chromate plated steel construction provides a robust barrier against rust and degradation, significantly prolonging fastener life in outdoor or moisture-rich environments. The square neck design effectively counters rotational forces, preventing bolt slippage in vibrating machinery like plows, construction equipment, and heavy-duty attachments. With a partially threaded shank and UNC coarse threads, installation is streamlined while maintaining strong grip strength. This combination of high tensile strength and corrosion resistance makes these bolts ideal for securing blades, blades, and structural components, reducing maintenance downtime and enhancing operational safety.

Specification Summary & Compliance

These plow bolts adhere to precise dimensional standards, including Class 2A thread fit for consistent tolerance and UNC coarse threading (3/4"-10 size) to facilitate quick assembly. Manufacturing complies with SAE J429 specifications, ensuring material integrity and performance reliability. The zinc yellow-chromate plating meets common industry requirements for corrosion protection, while the Rockwell C33 hardness and 150,000 psi tensile strength validate their suitability for heavy-duty applications. No specific RoHS or REACH declarations are provided, but the materials and processes align with typical industrial fastener regulations for safe use.
