Bowmalloy BOWMP36787 Hex Lock Nut 3/4-10 Grade 9

Product Description

The BOWMALLOY BOWMP36787 is a Grade 9 steel hex lock nut designed for high-strength fastening applications where vibration resistance and joint integrity are critical. It features a 3/4-10 inch thread size with right-hand threading and a Bowma-Guard finish for corrosion protection. The nut measures 1-7/64 inches (1.1094 inches decimal) across the flats and has a height of 0.724 inches. Installers working in heavy industrial, mechanical, or structural applications rely on this nut where standard-grade hardware is insufficient and elevated clamping force is required.

This hex lock nut is suited for demanding mechanical assemblies in industrial, commercial, and heavy-equipment environments. It is appropriate for use in structural connections, machinery mounting, and any bolted joint subject to dynamic loads or vibration. The 3/4-10 thread size is a common coarse-thread specification used across a wide range of mechanical and structural applications. Machinists, millwrights, maintenance technicians, and field mechanics routinely install this fastener as part of both OEM assemblies and field repairs.

Key Features

• Grade 9 steel construction provides high tensile strength and resistance to mechanical stress
• Bowma-Guard finish offers corrosion protection for extended service life
• 3/4-10 right-hand thread conforms to standard inch fastener specifications
• Width across flats of 1-7/64 inches (1.1094 inches) for standard wrench engagement
• Hex lock nut design resists loosening under vibration and dynamic loading

Compatibility

Designed for use with 3/4-10 inch coarse-thread bolts and studs in inch-series fastener assemblies requiring Grade 9 strength ratings.

Installation Notes

This fastener is installed by machinists, millwrights, and maintenance mechanics using standard hex wrenches or impact tooling sized for a 1-7/64-inch across-flats dimension. Always ensure mating fasteners meet or exceed the Grade 9 specification to maintain joint integrity. De-energize, depressurize, or otherwise render safe any equipment before servicing fasteners in live systems. Follow applicable industry standards and equipment manufacturer torque guidelines when making final assembly.
