Professional Applications & Engineering Value
This 3/8"-16 UNC rounded head slotted screw delivers critical engineering advantages where corrosion resistance and mechanical reliability are paramount. The 18-8 stainless steel construction, enhanced by passivated finish, provides exceptional protection against chemical exposure and atmospheric corrosion in marine, food processing, and chemical plant applications. The coarse UNC threading with Class 2A fit ensures rapid installation and superior vibration resistance in machinery assembly, while the partially threaded configuration allows precise positioning in structural frameworks. With 100,000 psi tensile strength and Rockwell B100 hardness, these industrial screws maintain clamping force integrity under dynamic loads, making them ideal for heavy equipment, conveyor systems, and permanent structural fastening where disassembly is infrequent.
Specification Summary & Compliance
This rounded head screw features precise 3/8"-16 UNC coarse threading with Class 2A thread fit tolerance for consistent engagement. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, meeting the latest compliance standards as of June 2023.
