Professional Applications & Engineering Value

This galvanized steel hex jam nut set addresses critical challenges in industrial fastening where corrosion resistance and thread versatility are paramount. The zinc-coated surface provides a protective barrier against moisture and chemicals, significantly extending service life in outdoor or corrosive environments. Engineered with both left-hand and right-hand UNC coarse threads, these nuts offer exceptional flexibility for specialized assemblies requiring counter-rotational security, particularly in turnbuckle systems and machinery where reverse threading prevents unintended loosening. The Class 2B thread fit maintains precise tolerances while accommodating minor variations in mating components, reducing installation time without compromising joint integrity. This combination of material durability and thread design makes these nuts ideal for construction, agricultural equipment, and industrial maintenance applications demanding reliable, long-term fastening solutions.

Specification Summary & Compliance

This hex jam nut set features 5/16"-18 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring proper clearance and engagement with Class 2A external threads. The nuts measure 1/2" across flats with a 3/16" height, manufactured from Grade 2 galvanized steel for consistent mechanical properties. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations confirms adherence to strict environmental and safety standards for industrial fastener applications.
