Overview

The NSi Industries JG5HSF51658 is a precision-engineered 5/16-18 x 5/8" indented hex head serrated flange screw made from Grade 5 zinc-plated steel. This full-thread screw features 18 threads per inch with a 5/16" major diameter, delivering robust clamping force in heavy-duty assemblies. The serrated flange under the head bites into mating surfaces to prevent loosening under vibration, while the indented hex recess allows for secure drive with standard tools and reduces cam-out. Zinc plating provides 500+ hours of salt spray corrosion resistance per ASTM B117, making it suitable for outdoor and industrial environments. The screw is ideal for machinery frames, automotive subassemblies, and structural connections where reliable preload and long-term stability are required. Compatible with standard 5/16" clearance holes and Grade 5 nut counterparts. Backed by NSi Industries' manufacturing quality system.
