Professional Applications & Engineering Value
These 316 stainless steel hex head screws deliver exceptional performance in demanding industrial applications where corrosion resistance and mechanical strength are critical. The UNF fine threading (7/16"-20) provides superior vibration resistance in machinery, automotive, and marine equipment, preventing loosening under dynamic loads. The external hex drive enables high-torque installation without cam-out, while the partial threading design allows the unthreaded shank to act as a precision dowel in assembled components. With 70,000 psi tensile strength and Rockwell B70 hardness, these fasteners maintain structural integrity in high-stress applications, from chemical processing equipment to offshore structures exposed to saltwater environments.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 specifications with Class 2A thread fit tolerance for consistent assembly performance. The 7/16"-20 UNF fine thread configuration ensures precise engagement, while the 1 3/4" length with 1 1/8" minimum thread length provides optimal fastening depth. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these screws suitable for global industrial applications requiring strict chemical substance control.
