Bowmalloy BOW36787 Hex Lock Nut 3/4-10 Grade 9 Steel

Product Description

The BOWMALLOY BOW36787 is a Grade 9 steel hex lock nut engineered for high-strength fastening applications where vibration resistance and thread retention are critical. Sized at 3/4-10 UNC, it features a right-hand thread direction and a Bowma-Guard finish coating for corrosion resistance. The nut measures 1.0938 inches (1-3/32 inches) across the flats and 0.726 inches in height. This part is sold in packages of 25 and is suited for installation by mechanical contractors, millwrights, and industrial maintenance technicians working with heavy-duty bolted assemblies.

The BOW36787 is designed for use in applications requiring superior clamping force and resistance to loosening under dynamic or vibrating loads. Grade 9 steel provides higher tensile and proof load ratings than standard Grade 5 or Grade 8 hardware, making this nut appropriate for heavy equipment, structural assemblies, and industrial machinery. Typical installation scenarios include flanged connections, equipment mounting, and structural steel work where a reliable locking fastener is required.

Compatibility

Designed as a high-strength replacement hex lock nut for 3/4-10 UNC threaded fastener assemblies requiring Grade 9 material specification.

Installation Notes

Installation should be performed by a qualified mechanic or industrial maintenance technician. De-energize and lock out all equipment before performing fastener service on live machinery. Use a properly sized wrench or socket matched to the 1-3/32 inch across-flats dimension to avoid rounding. Follow applicable torque specifications from the equipment manufacturer or relevant fastener standards when tightening Grade 9 hardware.
