Professional Applications & Engineering Value
This 1/2"-13 UNC hex head screw in 18-8 stainless steel provides exceptional engineering value for industrial applications where corrosion resistance and mechanical strength are critical. The coarse thread configuration ensures reliable performance in materials prone to stripping or where rapid assembly is required. With its external hex drive and substantial 3/4" head width, this fastener delivers superior torque transmission for heavy-duty connections in machinery, structural frameworks, and equipment manufacturing. The partially threaded design allows for precise joint compression while maintaining unthreaded shank strength, making it ideal for applications requiring specific clamp load distribution. These industrial hex screws withstand demanding environmental conditions while maintaining their mechanical integrity, reducing maintenance frequency and replacement costs.
Specification Summary & Compliance
This hex head screw features Class 2A thread fit tolerance for reliable engagement and meets ASME B18.2.1 dimensional standards. The fastener maintains 1/2"-13 UNC coarse thread specifications with a minimum thread length of 1-1/4" and overall length of 2-3/4". Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance for industrial applications.
