Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw delivers exceptional engineering value through its 18-8 stainless steel composition and partially threaded design. The material's inherent corrosion resistance makes it ideal for outdoor equipment, marine applications, and chemical processing facilities where environmental exposure is a concern. The coarse thread configuration provides superior holding power in softer materials and faster assembly in production environments. With Rockwell B70 hardness and 80,000 psi tensile strength, this external hex drive screw maintains structural integrity in heavy machinery, construction frameworks, and industrial assemblies where vibration resistance and long-term reliability are critical. The 9-1/2" length with 1-1/4" minimum thread length offers versatility for various thickness combinations while ensuring sufficient threaded engagement.
