Professional Applications & Engineering Value
These 2-56 UNC hex head screws deliver critical performance where corrosion resistance and mechanical reliability are paramount. The 18-8 stainless steel composition prevents rust and degradation in moisture-rich or chemically aggressive settings, while the coarse thread spacing and Class 2A thread fit enable rapid installation with reduced cross-threading risk. The fully threaded 1/2" length ensures uniform stress distribution, making these external hex drive fasteners ideal for machinery assembly, electronic enclosures, and structural components requiring repeated maintenance access. Their compliance with ASME B18.6.3 guarantees dimensional consistency for replacement and inventory management.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 standards with Class 2A thread fit tolerances for consistent engagement. The UNC coarse thread (2-56) features right-hand direction and 0.086" diameter. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures adherence to environmental and safety requirements for industrial components.
