Professional Applications & Engineering Value
This 18-8 stainless steel hex head screw delivers exceptional engineering value for industrial applications where corrosion resistance and mechanical strength are critical. The 1/2"-20 UNF fine thread configuration provides superior vibration resistance compared to coarse threads, making it ideal for machinery, automotive components, and precision equipment that experience dynamic loads. The external hex drive enables high-torque installation without stripping, while the Rockwell B70 hardness ensures the screw maintains its structural integrity under repeated stress. The fully threaded design along the entire 2 3/4" length allows for maximum engagement in thick materials or when precise adjustment is required, solving common assembly challenges in manufacturing and construction applications.
Specification Summary & Compliance
This hex head screw features precision Class 2A thread fit with 1/2"-20 UNF fine threading and right-hand thread direction. Manufactured from 18-8 stainless steel with 80,000 psi tensile strength and Rockwell B70 hardness, the fastener meets industry standards for mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
