Professional Applications & Engineering Value

This 1"-12 UNF fine thread hex nut delivers exceptional performance in demanding sectors like heavy machinery, automotive assembly, and structural frameworks. Crafted from Black-Oxide 18-8 Stainless Steel, it combats rust and chemical exposure, a common failure point in humid or corrosive settings. The fine thread spacing increases tensile strength and provides superior resistance to loosening under dynamic loads, making it ideal for vibration-prone applications. Its Class 2B thread fit ensures smooth, precise mating with UNF bolts, reducing the risk of cross-threading and enhancing assembly efficiency. This nut is a reliable choice for engineers seeking long-term durability and reduced lifecycle costs in industrial fastening solutions.

Specification Summary & Compliance

This hex nut adheres to UNF (Unified National Fine) thread standards with a Class 2B thread fit for consistent dimensional accuracy. Key measurements include a 1"-12 fine thread size, 1 1/2" width, and 55/64" height. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its compliance with international environmental and safety standards for industrial components.
