Professional Applications & Engineering Value

This Grade 8 plow bolt is engineered to address common challenges in heavy-duty and agricultural machinery, where vibration, high loads, and exposure to the elements can compromise fastener integrity. The zinc yellow-chromate plated steel construction resists corrosion, while the square neck effectively counters rotation in plow shares, cutting edges, and other implements. The partially threaded design with UNC coarse threads ensures quick, secure fastening in thick steel plates, reducing assembly time and maintenance needs. Ideal for snow plows, earth-moving equipment, and agricultural attachments, this bolt delivers reliable performance under demanding conditions, minimizing downtime and replacement costs.

Specification Summary & Compliance

The bolt features a 3/4"-10 UNC thread with Class 2A fit for precise dimensional tolerance, and is manufactured in compliance with SAE J429 standards. It includes a square neck width of 0.77" and oval head profile, with partial threading (minimum 1 3/4" thread length). The material and plating meet common industry requirements for performance and environmental regulations.
