Bowmalloy 36787 Hex Lock Nut 3/4-10 Grade 9 Steel

Product Description

The BOWMALLOY 36787 is a Grade 9 steel hex lock nut with a 3/4-10 thread size, designed to maintain clamping force in high-vibration and high-stress fastening applications. The cadmium waxed finish provides corrosion resistance and reduces galling during installation and removal. At 0.726 inches in height with a width across flats of 1-3/32 inches, this nut meets inch-standard dimensions for direct use with matching 3/4-10 threaded fasteners. It is used by industrial maintenance technicians, millwrights, and mechanical contractors working on heavy equipment, structural assemblies, and machinery requiring reliable thread locking without adhesive compounds.

This hex lock nut is suited for industrial and commercial fastening applications where standard nuts are prone to loosening under vibration or dynamic loading. The right-hand thread orientation is compatible with conventional 3/4-10 threaded rod, bolts, and studs used across mechanical, structural, and equipment-mounting scenarios. The Grade 9 steel construction offers higher proof load and tensile strength than Grade 5 or Grade 8 nuts, making it appropriate for demanding service conditions. Sold in a package quantity of 25 units.

Installation Notes

Installation should be performed by qualified mechanical or industrial maintenance personnel using a properly sized wrench or socket matched to the 1-3/32 inch width across flats. De-energize or lock out any equipment before fastener service to comply with applicable OSHA lockout/tagout procedures. Cadmium-coated fasteners require appropriate handling precautions per safety data sheet guidelines. Do not reuse lock nuts that show signs of thread damage or deformation.
