Bowmalloy 36604 Hex Nut 7/16-14 Grade 9 Zinc-plated

Product Description

The BOWMALLOY 36604 is a Grade 9 steel hex nut with a 7/16-14 thread size and a zinc-plated clear chromate finish. Grade 9 fasteners are manufactured to meet higher tensile and proof-load requirements than Grade 5 or Grade 8, making this nut well suited for high-stress bolted connections. The clear chromate zinc plating provides a baseline level of corrosion resistance for general industrial and mechanical applications. With a hardness range of 26-36 HRC and dimensions conforming to ANSI/ASME B18.2.2, this nut is installed by mechanical technicians, millwrights, and maintenance professionals wherever a reliable high-strength threaded connection is required.

This hex nut is appropriate for use in industrial machinery, heavy equipment assemblies, structural fastening, and other applications where Grade 9 strength is specified. Its right-hand thread engages standard 7/16-14 UNC bolts and threaded rod. The package quantity is 50 pieces per package with a minimum order quantity of 1 package, making it practical for both single-repair jobs and higher-volume maintenance work.

Installation Notes

Installation is performed by qualified mechanical or maintenance personnel using a standard 11/16-inch wrench or socket. Always de-energize or shut down equipment before replacing or installing fasteners on operating machinery. Do not mix Grade 9 nuts with lower-grade fastener hardware in the same joint assembly. Follow applicable torque specifications from the equipment manufacturer or relevant mechanical codes for the specific bolted joint.
