Bowmalloy BOW36618 Hex Nut 3/4-16 Grade 9 Steel

Product Description

The BOWMALLOY BOW36618 is a Grade 9 steel hex nut with a 3/4-16 thread size, designed for high-strength fastening applications where standard hardware grades fall short. It carries a Bowma-Guard zinc-plated clear chromate finish that provides corrosion resistance without sacrificing dimensional precision. The nut measures 1.093 inches across flats and 0.637 inches in height, conforming to ANSI ASME B18.2.2 standards. Hardness is rated at 26-36 HRC. Machinists, millwrights, and industrial maintenance technicians typically specify Grade 9 hardware in high-load or high-vibration assemblies where SAE Grade 5 or Grade 8 fasteners are insufficient.

This hex nut is suited for heavy equipment, industrial machinery, and structural assemblies that demand maximum clamp load. The right-hand thread pattern is the standard orientation for most mechanical systems. Grade 9 hardware is commonly found in agricultural equipment, mining machinery, and heavy transport applications. The Bowma-Guard finish makes it viable in environments with moderate moisture or chemical exposure. Sold in packages of 25 units, it is well suited to shop stock, maintenance kits, and service truck inventory.

Compatibility

Designed as a Grade 9 replacement or new-installation hex nut for 3/4-16 UNF threaded fastener applications conforming to ANSI ASME B18.2.2 specifications.

Installation Notes

Install using a standard 1-3/32 inch hex wrench or socket rated for the applied torque. Always verify the mating bolt is also rated Grade 9 or equivalent before assembly to prevent fastener mismatch under load. Power down and de-energize any machinery before servicing fasteners in mechanical assemblies. Follow the equipment manufacturer torque specifications and applicable ASME or industry standards for the specific application.
