Professional Applications & Engineering Value
These Grade 5 zinc-plated steel hex head screws deliver exceptional engineering value in industrial assemblies where vibration resistance and structural integrity are critical. The UNF fine threading provides superior holding power in softer materials and high-vibration environments, while the flange design eliminates the need for separate washers, distributing clamp load effectively across wider surfaces. The Rockwell C22 hardness rating ensures excellent wear resistance during repeated installations, making these fully threaded screws ideal for machinery, automotive subsystems, and heavy equipment where 110,000 PSI tensile strength is required to withstand dynamic loads and stress cycles without failure.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent engagement. Complies with SAE J429 specifications for Grade 5 mechanical properties and meets IFI 111 requirements. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restricted substance adherence for global industrial applications.
