- Environmental compliance with RoHS 3 and REACH standards for safe usage across regulated industries
- Optimized load distribution from the extra wide design that reduces surface pressure and prevents embedding
Professional Applications & Engineering Value
This hot-dipped galvanized steel hex nut delivers exceptional engineering value where corrosion resistance and structural integrity are paramount. The Grade 2H certification ensures reliable performance in high-vibration environments such as construction equipment, structural steel assemblies, and heavy machinery. The extra wide profile provides greater bearing surface, distributing clamp load more effectively to prevent joint relaxation. Combined with UNC coarse threading, these nuts enable rapid assembly in field applications while maintaining Class 2B thread fit precision. The hot-dipped galvanized coating offers superior protection against rust and corrosion, making these industrial hex nuts ideal for outdoor infrastructure, marine applications, and chemical processing facilities where environmental exposure is a constant challenge.
Specification Summary & Compliance
This 1/4"-20 UNC hex nut features Class 2B thread fit tolerance and right-hand thread direction, manufactured to ASTM A194 specifications for high-strength applications. The fastener meets ASTM Grade 2H strength requirements with dimensions of 1/2" width and 15/64" height. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures environmental safety standards are maintained for industrial usage across global markets.
