Professional Applications & Engineering Value
This 3/8"-24 UNF hex nut in 18-8 stainless steel is engineered to address critical challenges in industrial settings, such as corrosion from chemicals or moisture, and vibration-induced fastener failure. The fine thread design provides more threads per inch compared to coarse threads, offering superior clamping force and resistance to loosening under stress, which is vital in machinery, automotive, and aerospace assemblies. The Class 2B thread fit ensures smooth engagement with mating bolts, reducing the risk of cross-threading and improving installation efficiency. With an external hex drive, it allows for high-torque applications using standard tools, making it a reliable choice for maintenance and production lines where durability and compliance with RoHS and REACH standards are non-negotiable for safety and environmental responsibility.
Specification Summary & Compliance
This hex nut adheres to UNF (Unified National Fine) thread standards with a Class 2B thread fit for consistent dimensional accuracy. It features a 3/8"-24 fine thread size, standard hex profile, and right-hand thread direction. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for industrial and export markets.
