Professional Applications & Engineering Value

This Grade 2 steel hex nut with 1½"-6 UNC coarse threading delivers exceptional engineering value in heavy machinery, structural steelwork, and industrial equipment assembly. The extra-wide thin profile fundamentally addresses common failure points in high-vibration environments by distributing clamp load across a broader surface area, significantly reducing the risk of joint loosening and material fatigue. The Class 2B thread fit ensures precise mating with corresponding external hex drive components while accommodating minor misalignments during installation. Manufactured from robust steel and compliant with international inch measurement standards, this fastener provides reliable performance in construction equipment, agricultural machinery, and transportation infrastructure where coarse thread fasteners are preferred for their resistance to clogging and rapid assembly capabilities.

Specification Summary & Compliance

This industrial hex nut features precise 1½"-6 UNC coarse threading with Class 2B thread fit per ASME B1.1 standards, ensuring proper engagement with mating components. Dimensional specifications include a 2⅜" width across flats and 27/32" height for the extra-wide thin profile configuration. The fastener meets Grade 2 strength classification requirements and is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming absence of restricted hazardous substances. Right-hand thread direction and external hex drive style provide standard industrial compatibility for reliable performance across various applications.
