Professional Applications & Engineering Value
These 18-8 stainless steel hex head screws deliver exceptional engineering value across industrial applications where corrosion resistance and mechanical strength are critical. The 7/16"-20 UNF fine threading with Class 2A fit provides superior vibration resistance in machinery, automotive assemblies, and structural frameworks. The partially threaded design concentrates clamping force precisely where needed, preventing joint loosening while the external hex drive accommodates high-torque installation in confined spaces. Manufactured from stainless steel with 80,000 psi tensile strength, these screws maintain integrity in corrosive environments including chemical processing, marine applications, and outdoor infrastructure where moisture and chemicals would compromise ordinary fasteners.
Specification Summary & Compliance
This 3 1/4" length hex head screw features 7/16"-20 UNF fine threading with precision Class 2A thread fit according to inch system standards. The partially threaded configuration provides optimal clamping performance with 1 1/8" minimum thread length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while delivering Rockwell B70 hardness and 80,000 psi tensile strength for reliable industrial performance.
