Professional Applications & Engineering Value

This 7/8"-9 UNC Hex Head Screw in 316 Stainless Steel is engineered to solve critical challenges in industrial and marine environments where corrosion resistance and structural integrity are paramount. The coarse thread design combined with a Class 2A thread fit ensures rapid assembly and vibration resistance in heavy machinery, structural steelwork, and chemical processing equipment. Its partial threading provides an unthreaded shank for precise shear load distribution, while the external hex drive allows for high-torque application, preventing stripping and ensuring a secure, long-lasting connection even under sustained stress and exposure to corrosive agents.

Specification Summary & Compliance

This screw adheres to ASME B18.2.1 specifications, ensuring precise dimensional standards for the hex head, thread form, and overall geometry. The UNC coarse thread is manufactured to Class 2A tolerance, providing consistent fit and interchangeability. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use worldwide.
