Bowmalloy BOW36802 Hex Lock Nut 3/4-16 Grade 9

Product Description

The BOWMALLOY BOW36802 is a Grade 9 steel hex lock nut with a 3/4-16 thread size and a Bowma-Guard finish. It is engineered for high-strength fastening applications where vibration resistance and corrosion protection are critical. The nut measures 1.0938 inches (1-3/32 inches) across the flats and has a decimal height of 0.726 inches. The Bowma-Guard finish provides a cadmium waxed surface that helps resist corrosion and reduces galling during installation. Grade 9 steel construction delivers higher tensile and proof load ratings than standard Grade 5 or Grade 8 hardware, making this nut appropriate for demanding mechanical and structural assemblies.

This hex lock nut is suited for use in mechanical, industrial, and heavy-duty structural applications where high-strength fasteners are specified. It uses a right-hand thread direction and follows the inch measurement system, compatible with standard 3/4-16 UNF threaded bolts and studs. Typical install scenarios include equipment assemblies, power transmission mounting, and industrial machinery where vibration and torque loads require reliable locking performance. Trade professionals in HVAC equipment assembly, industrial maintenance, and mechanical contracting will find this nut appropriate for high-load fastening points.

Key Features

• Grade 9 steel construction for high tensile and proof load strength
• 3/4-16 UNF right-hand thread for standard inch-system compatibility
• Bowma-Guard cadmium waxed finish for corrosion and galling resistance
• Width across flats: 1.0938 inches (1-3/32 inches) for standard hex tooling

• Sold in package quantities of 25 per order

Compatibility

Designed as an OEM-style replacement or direct-fit hex lock nut for assemblies using 3/4-16 UNF threaded fasteners in Grade 9 or equivalent high-strength applications.

Installation Notes

Installation should be performed by a qualified mechanic or industrial technician familiar with high-strength fastener specifications. Always verify that the mating bolt or stud is also rated for Grade 9 or higher before applying final torque. Use appropriate hex wrenching tools sized for a 1.0938-inch across-flats dimension. De-energize, lock out, and tag out any equipment before servicing fasteners on powered machinery.
