Professional Applications & Engineering Value
This 7/8"-9 UNC hex head screw delivers critical performance where structural integrity and corrosion resistance are paramount. Manufactured from 18-8 Stainless Steel, it combats rust and chemical exposure in marine, chemical processing, and outdoor construction applications. The coarse UNC threads provide excellent holding power in brittle materials or where vibration loosening is a concern, while the fully threaded design ensures consistent clamping force across the entire 1 1/2" length. The external hex drive and substantial head size allow for high torque application, making it a preferred heavy-duty fastening solution for machinery assembly, structural steel connections, and industrial equipment maintenance.
Specification Summary & Compliance
This screw features a 7/8"-9 UNC thread with Class 2A fit for consistent dimensional accuracy and assembly ease. It is manufactured in compliance with ASME B18.2.1 standard for hex head screws, ensuring reliable mechanical properties and interchangeability. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for use in regulated markets and environmentally conscious projects.
