Professional Applications & Engineering Value

These Grade 5 Plow Bolts are engineered to address critical challenges in agricultural and industrial equipment, where vibration and heavy loads can compromise fastener integrity. The zinc-plated steel material offers robust resistance to rust and wear, while the square neck mechanically locks the bolt in place to prevent rotation during operation—eliminating the need for additional locking devices. With fully threaded UNC coarse threading and a Class 2A thread fit, they ensure rapid installation and high clamp force retention in components like plow blades, conveyor systems, and construction machinery. This design reduces maintenance downtime and enhances safety, making them ideal for heavy-duty fastening applications that demand durability and reliability under cyclic stresses.

Specification Summary & Compliance

This product adheres to precise dimensional standards, including a Class 2A thread fit for consistent engagement and UNC coarse threading (3/8"-16) per industry norms. Manufacturing and material specifications comply with ASME B18.9 and SAE J429 for Grade 5 bolts, ensuring tensile strength and hardness (Rockwell C25) meet rigorous engineering requirements. Additionally, it is verified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, supporting use in environmentally regulated markets without hazardous substance restrictions.
