Professional Applications & Engineering Value

This Grade 5 steel hex nut with left-hand UNC coarse threading delivers critical reverse-threading security for industrial machinery, conveyor systems, and rotating equipment where standard right-hand threads would naturally loosen. The 1 1/2"-6 thread size combined with Class 2B thread fit provides optimal clearance for rapid assembly while maintaining vibration resistance in high-stress applications. Manufactured from medium-carbon steel with external hex drive, this fastener withstands substantial clamping forces while enabling quick maintenance access. The coarse thread design proves particularly valuable in applications involving frequent disassembly or environments prone to debris accumulation, ensuring reliable performance in manufacturing, heavy equipment, and infrastructure projects.

Specification Summary & Compliance

This heavy-duty hex nut features 1 1/2"-6 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and reliable mating with corresponding fasteners. The Grade 5 strength classification confirms consistent mechanical properties meeting industry specifications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these nuts suitable for global industrial applications requiring verified material safety and regulatory compliance.
