Professional Applications & Engineering Value
This Grade 5 steel hex nut delivers exceptional engineering value through its optimized material selection and thin profile design. The 1/4"-20 UNC coarse thread configuration provides rapid assembly in high-volume production environments while maintaining vibration resistance. The Class 2B thread fit ensures consistent engagement with mating bolts, reducing the risk of stripping and galling during repeated installations. Particularly valuable in industrial applications where space constraints challenge conventional fasteners, this external hex nut maintains full ASME B18.2.2 compliance while offering a lower profile solution. The combination of steel material and proper heat treatment provides excellent strength-to-weight ratio, making it ideal for machinery, equipment assembly, and structural frameworks requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
This hex nut features precise 1/4"-20 UNC coarse threads with Class 2B thread fit tolerance, manufactured to ASME B18.2.2 specifications. The dimensional accuracy includes a 7/16" width across flats and 5/32" height for the thin profile configuration. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while maintaining the mechanical properties required for Grade 5 strength classification.
