Value Collection 444010PS Hex Nut 1/2-13 Grade L9 Steel

Product Description

The VALUE COLLECTION 444010PS is a 1/2-13 UNC hex nut manufactured from Grade L9 steel and finished with a zinc yellow dichromate, cadmium, and wax coating. Grade L9 designates a high-strength, prevailing-torque classification used in demanding mechanical and structural fastening applications. The zinc yellow dichromate finish combined with a wax topcoat provides corrosion resistance and reduces thread friction during installation. This nut measures 3/4 inches across the flats and 7/16 inch in height, conforming to standard 1/2-13 UNC thread geometry with a right-hand thread direction. It is suited for use by maintenance technicians, millwrights, and general tradespeople working in industrial, mechanical, or structural assembly contexts.

This hex nut is intended for use in bolted assemblies requiring a high-strength 1/2-13 UNC fastener with corrosion-resistant surface treatment. Typical applications include industrial equipment assembly, structural steel connections, and mechanical maintenance work where Grade L9 material properties are specified. The waxed finish aids in consistent torque values during assembly. This nut does not meet military specifications and is not rated for military-grade applications.

Key Features

• Grade L9 steel construction for high-strength fastening applications
• Zinc yellow dichromate and cadmium finish plus wax topcoat for corrosion resistance and reduced thread friction
• 1/2-13 UNC right-hand thread for compatibility with standard 1/2-13 bolts and studs
• 3/4 inch across flats, 7/16 inch height — standard hex nut profile
• Right-hand thread direction for conventional wrench-tightening installations

Compatibility

Designed as a standard hex nut for use with 1/2-13 UNC threaded fasteners in industrial, mechanical, and structural assemblies requiring Grade L9 steel and a corrosion-resistant finish.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with fastener torque requirements for Grade L9 hardware. Ensure mating bolt or stud threads are clean and free of debris before installation. Apply consistent torque using a calibrated torque wrench — refer to the applicable engineering specification or fastener manufacturer data for the correct torque value for this thread size and material grade. Do not mix Grade L9 nuts with lower-grade fasteners in high-load assemblies.
