Professional Applications & Engineering Value

This heavy-duty 1 3/4"-5 UNC extra wide hex nut delivers exceptional engineering value through its 316 stainless steel composition and optimized design. The coarse thread configuration significantly reduces cross-threading risks during installation while maintaining vibration resistance in high-stress environments. The extra wide hex profile addresses critical load distribution challenges by increasing bearing surface area, effectively preventing joint loosening and material crushing in structural applications. Particularly valuable in marine, chemical processing, and heavy machinery sectors, this nut's corrosion-resistant properties combat degradation from saltwater, chemicals, and atmospheric exposure. The external hex drive ensures compatibility with standard industrial tools, streamlining maintenance procedures while the Class 2B thread fit guarantees consistent performance across repetitive assembly cycles.

Specification Summary & Compliance

Manufactured to precise inch system dimensions (2 3/4" width, 1 23/32" height) with UNC coarse thread specification and Class 2B thread fit tolerance for reliable mating with corresponding male threads. This right-hand threaded hex nut complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for industrial and international applications. The 316 stainless steel construction meets industry standards for corrosion resistance and mechanical performance in demanding operating conditions.
