Bowmalloy 36799 Hex Lock Nut 1/2-20 Grade 9 Steel

Product Description

The BOWMALLOY 36799 is a Grade 9 steel hex lock nut engineered for high-strength fastening applications where vibration resistance and joint integrity are critical. It carries a 1/2-20 thread size with right-hand thread direction, a width across flats of 0.75 inches, and a height of 0.435 inches. The cadmium waxed finish provides corrosion resistance and reduces galling during installation. This nut is suited for mechanical assemblies, structural connections, and equipment used in trade service environments where standard Grade 5 or Grade 8 hardware is insufficient.

The 36799 is used in applications requiring a higher-grade fastener than typical hardware-grade nuts. Grade 9 steel offers elevated proof load and tensile strength compared to common grades, making it appropriate for heavy equipment, industrial machinery, and high-load mechanical joints. Typical installers include millwrights, mechanical contractors, and service technicians working on equipment with demanding fastener specifications. It ships in a package quantity of 50.

Compatibility

Designed as a high-strength hex lock nut for 1/2-20 inch-threaded fastener applications requiring Grade 9 material and cadmium waxed finish.

Installation Notes

Install and remove using a 3/4-inch wrench or socket driver. Power down or de-energize any associated equipment before working in fastener-accessible areas. Follow applicable torque specifications from the equipment manufacturer or relevant ASME or ASTM fastener standards for Grade 9 hardware. Avoid mixing fastener grades within the same joint assembly.
