Bowmalloy BOWMP36783 Hex Lock Nut 7/16-14 Grade 9

Product Description

The BOWMALLOY BOWMP36783 is a Grade 9 steel hex lock nut designed for high-strength fastening applications. It features a 7/16-14 inch thread size with right-hand threading and a Bowma-Guard finish that provides corrosion resistance in demanding environments. Standing 3/8 inches high with a width across flats of 11/16 inches, this nut is engineered to maintain clamp load and resist loosening under vibration and dynamic loads. It is suited for mechanical assemblies where fastener integrity is critical and where a durable protective coating is required.

This hex lock nut is used across a range of industrial and mechanical installation scenarios, including HVAC equipment mounting, structural brackets, pump and motor assemblies, and general mechanical fastening tasks. The Grade 9 material classification indicates high tensile strength, making this nut appropriate for applications requiring a step up from standard Grade 5 or Grade 8 hardware. It ships in packages of 25, making it practical for service technicians and contractors who need reliable inventory on hand.

Installation Notes

Installation is typically performed by mechanical contractors, HVAC technicians, or industrial maintenance professionals using standard combination or socket wrenches sized for 11/16 inch flats. Always de-energize or shut down the equipment assembly before servicing fasteners on live mechanical or electrical systems. Verify thread compatibility and torque requirements per the equipment manufacturer's specifications before final tightening. Do not mix fastener grades within a single joint assembly.
