• Compliance with major industrial standards including ASME B18.2.1, RoHS 3, and REACH

Professional Applications & Engineering Value

This 3/4"-10 UNC hex head screw in 316 stainless steel is engineered to address critical challenges in demanding industrial settings. Its coarse thread design provides faster installation and superior resistance to vibration loosening in heavy machinery, structural frameworks, and marine equipment. The fully threaded configuration ensures uniform stress distribution along the entire 4 1/2" length, enhancing joint integrity. With an external hex drive and high tensile strength, it delivers reliable performance in corrosive environments where fastener failure is not an option, making it ideal for chemical processing, offshore platforms, and wastewater treatment facilities.

Specification Summary & Compliance

This screw features a 3/4"-10 UNC coarse thread with Class 2A thread fit for standard tolerance and interchangeability. It is manufactured in compliance with ASME B18.2.1 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental and safety standards are upheld for industrial use.
