Professional Applications & Engineering Value
This 1"-8 UNC hex head screw in 316 stainless steel delivers critical performance advantages for demanding industrial applications. The coarse thread design provides faster assembly in structural connections, while the partial threading maintains maximum shank strength where full threads aren't required. The external hex drive accommodates high installation torque without cam-out, making it ideal for machinery assembly, structural steel connections, and marine equipment where corrosion resistance is paramount. With Rockwell B70 hardness and 70,000 psi tensile strength, this fastener withstands vibration and dynamic loads in construction, chemical processing, and offshore applications where reliability cannot be compromised.
Specification Summary & Compliance
This 4 1/2" length hex head screw features 1"-8 UNC coarse threads with Class 2A thread fit tolerance for precise engagement. Manufacturing conforms to ASME B18.2.1 dimensional standards, ensuring interchangeability and consistent performance. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial markets requiring verified material composition and restricted substance compliance.
