Bowmalloy BOW36604 Hex Nut 7/16-14 Grade 9 Steel

Product Description

The BOWMALLOY BOW36604 is a Grade 9 steel hex nut with a 7/16-14 thread size, designed for high-strength fastening applications where standard hardware-grade fasteners are not sufficient. Finished with a zinc-plated clear chromate coating - marketed as Bowma-Guard - this nut resists corrosion while maintaining dimensional accuracy to ANSI/ASME B18.2.2 standards. The right-hand thread pattern and 11/16-inch across-flats dimension make it compatible with standard wrench tooling. With a hardness rating of 26-36 HRC, it is suited for demanding mechanical and structural assemblies. Mechanical contractors, millwrights, and industrial maintenance professionals typically specify Grade 9 fasteners where higher proof load and tensile strength are required over Grade 5 or Grade 8 equivalents.

This hex nut is appropriate for use in heavy equipment assembly, structural steel connections, and high-load mechanical joints in commercial and industrial settings. The 7/16-14 thread size is a common UNC coarse-thread specification found across a wide range of bolted connections in manufacturing, HVAC equipment frames, and utility infrastructure. Its zinc-plated finish makes it suitable for both indoor installations and moderately corrosive environments. Sold in packages of 50, it is practical for both service-call stocking and project-quantity purchasing.

Key Features

• Grade 9 steel construction with 26-36 HRC hardness for high-strength fastening
• Zinc-plated clear chromate (Bowma-Guard) finish for corrosion resistance
• 7/16-14 UNC right-hand thread per ANSI/ASME B18.2.2 standard
• 11/16-inch across-flats width fits standard SAE wrench and socket tooling
• Height of 0.328 inches for consistent seating in standard bolt applications
• Packaged in quantities of 50 for efficient job-site and shop inventory

Compatibility

Designed for use with 7/16-14 UNC threaded fasteners and bolts in high-strength mechanical and structural assemblies conforming to ANSI/ASME B18.2.2 specifications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel familiar with proper torque procedures for Grade 9 fasteners. Always ensure mating bolt grade is compatible with Grade 9 nut specifications before assembly. Clean threads of debris and inspect for damage before installation. Follow applicable industry or equipment manufacturer torque specifications - no torque values are provided with this fastener alone.
