Professional Applications & Engineering Value
This 7/8"-9 UNC hex head screw in 316 stainless steel delivers exceptional performance where corrosion resistance and structural integrity are paramount. The coarse thread configuration provides superior holding power in softer materials and faster installation times, while the external hex drive ensures maximum torque application without slippage. Engineered with partial threading, this fastener concentrates thread engagement where needed most, making it ideal for structural connections, heavy machinery assembly, and marine applications where saltwater corrosion would compromise ordinary fasteners. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures reliable performance under vibration and dynamic loading conditions common in industrial settings.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit with UNC coarse threading (7/8"-9) and meets dimensional requirements per ASME B18.2.1 standard. The fastener is manufactured from 316 stainless steel with a length of 5 1/2" and minimum thread length of 2". Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance management.
