Professional Applications & Engineering Value
This heavy-duty 7/8"-9 UNC hex head screw is engineered from 316 Stainless Steel to solve critical challenges in corrosive and high-stress environments. Its coarse thread design ensures rapid assembly and reliable performance in structural applications, marine equipment, chemical processing, and offshore installations. The external hex drive and robust head dimensions provide superior torque transmission, reducing the risk of stripping during installation. With a 70,000 PSI tensile strength and Rockwell B70 hardness, it maintains clamping force under vibration and load, preventing joint failure. The partial threading concentrates strength where needed, making it ideal for securing heavy machinery, flanges, and construction frameworks where long-term reliability is non-negotiable.
Specification Summary & Compliance
This screw features a Class 2A thread fit for consistent assembly and UNC coarse threads (7/8"-9) per standard inch system specifications. It is manufactured to meet ASME B18.2.1 dimensional and mechanical requirements, ensuring interchangeability and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated markets and environmentally conscious projects.
