Professional Applications & Engineering Value

Engineered for heavy-duty agricultural and industrial environments, this Grade 8 plow bolt delivers exceptional value through its robust construction. The zinc yellow-chromate plated steel provides superior corrosion protection against moisture, chemicals, and weathering commonly encountered in farming equipment and construction machinery. The square neck design effectively prevents rotation during vibration-intensive operations, eliminating the need for additional locking mechanisms. With 150,000 PSI tensile strength and Rockwell C33 hardness, this fastener maintains structural integrity under extreme loads, making it ideal for snow plow assemblies, earth-moving equipment, and heavy agricultural implements where failure is not an option. The partially threaded UNC coarse thread configuration ensures optimal clamping force distribution while facilitating quicker installation in field maintenance scenarios.

Specification Summary & Compliance

This 5/8"-11 plow bolt features Class 2A thread fit tolerance for precise engagement and meets SAE J429 specifications for quality assurance. The fastener maintains dimensional accuracy with 3" length, oval head profile, and 82° countersink angle for proper seating. Manufacturing complies with industry standards for Grade 8 strength classification, ensuring consistent performance across agricultural and industrial applications where reliability and durability are paramount.
