- Compliance with ASME B18.2.1 standards ensures dimensional accuracy and interchangeability
Professional Applications & Engineering Value
These 3/4"-16 UNF hex head screws deliver exceptional engineering value in demanding applications where corrosion resistance and mechanical strength are critical. The 18-8 stainless steel composition provides excellent protection against rust and chemical exposure, making them ideal for marine equipment, food processing machinery, and chemical processing plants. The fine thread configuration offers superior resistance to loosening under vibration, while the partially threaded design ensures that unthreaded portions bear against mating surfaces for maximum joint stability. With 80,000 psi tensile strength and Rockwell B70 hardness, these industrial hex screws maintain structural integrity in high-stress assemblies, from heavy machinery frames to structural steel connections.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 specifications with Class 2A thread fit tolerance for precision threading. The 3/4"-16 UNF fine thread configuration follows standardized inch system measurements with right-hand threading and external hex drive. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across various industries.
