Professional Applications & Engineering Value
This 2"-8 UN fine thread hex nut is engineered to address common challenges in heavy-duty industrial applications, such as structural steel connections, machinery assembly, and infrastructure projects. The ASTM Grade 2H steel construction delivers high clamp load retention, preventing loosening under vibration and thermal cycling. The extra wide profile increases bearing surface area, distributing stress more evenly and reducing the risk of joint failure in high-load scenarios. Combined with a Class 2B thread fit, it ensures precise engagement with mating bolts, minimizing play and enhancing overall assembly integrity. Ideal for construction, manufacturing, and oil and gas sectors, this nut provides reliable fastening solutions where safety and durability are paramount.
Specification Summary & Compliance
This hex nut features a 2"-8 UN fine thread with Class 2B fit for consistent dimensional accuracy, manufactured in compliance with ASTM A194 and ASTM Grade 2H strength requirements. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence in industrial use.
