Bowmalloy 36802 Hex Lock Nut 3/4-16 Grade 9 Steel

Product Description

The BOWMALLOY 36802 is a Grade 9 steel hex lock nut engineered for high-strength fastening applications where vibration resistance and thread integrity are critical. Sized at 3/4-16 UNF right-hand thread, this nut features a cadmium with wax finish that provides corrosion resistance and reduces galling during installation. At 0.726 inches in height and 1-3/32 inches width across flats, it is dimensionally suited for standard wrench and socket tooling. Installers in industrial, heavy equipment, and structural assembly work rely on Grade 9 hardware when fastener tensile demands exceed the capacity of Grade 5 or Grade 8 equivalents.

This hex lock nut is used in heavy-duty mechanical assemblies requiring secure thread engagement under dynamic or high-vibration loads. Typical applications include industrial machinery, hydraulic systems, and structural connections where fine-thread engagement provides higher clamping force per unit torque compared to coarse-thread alternatives. The 3/4-16 UNF specification is common in precision assemblies across manufacturing, agriculture, and construction equipment platforms.

Key Features

• Grade 9 steel construction for high tensile and proof load performance
• 3/4-16 UNF right-hand thread for fine-pitch engagement and maximum clamping force
• Cadmium with wax finish for corrosion protection and reduced installation friction
• 1-3/32 inches width across flats fits standard SAE wrench and socket sets
• 0.726 inches height provides full thread engagement depth
• Sold in quantities of 25 per package

Compatibility

Designed as an OEM-style replacement or service fastener for assemblies using 3/4-16 UNF Grade 9 hex lock nuts with cadmium-waxed finish requirements.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with high-strength fastener procedures. De-energize, depressurize, or mechanically lock out the assembly before replacing any structural fastener. Use a calibrated torque wrench appropriate for Grade 9 fastener specifications sourced from the equipment manufacturer's service documentation. Cadmium-finished fasteners should be handled in accordance with applicable safety guidelines due to the hazardous nature of cadmium compounds.
