Value Collection 444018BR Hex Nut 7/8-9 Grade L9 Steel

Product Description

The VALUE COLLECTION 444018BR is a heavy-duty hex nut threaded to a 7/8-9 UNC specification, manufactured from Grade L9 steel and finished with a zinc yellow dichromate, cadmium, and waxed coating. Grade L9 identifies this as a high-strength, prevailing-torque-style nut designed for demanding mechanical and structural fastening applications. The zinc yellow dichromate and cadmium finish provides corrosion resistance in environments where standard zinc plating is insufficient. This nut measures 1-5/16 inches across the flats and 3/4 inch in height, with a right-hand thread direction. It is installed by millwrights, maintenance mechanics, and structural assemblers working on industrial machinery, heavy equipment, and high-load structural connections.

This hex nut is suited for industrial and commercial fastening applications requiring elevated tensile strength and reliable corrosion protection. The 7/8-9 UNC thread size is common in heavy equipment frames, agricultural machinery, mining equipment, and structural steel assemblies. The waxed finish aids in consistent torque-to-clamp load performance during installation, which is important in controlled-torque assembly sequences. This part ships individually but requires a minimum order quantity of two units.

Key Features

• Grade L9 steel construction for high-strength fastening applications
• Zinc yellow dichromate and cadmium finish for enhanced corrosion resistance
• Waxed surface treatment supports consistent torque-to-clamp load characteristics
• 7/8-9 UNC right-hand thread for compatibility with standard unified coarse thread fasteners
• 1-5/16 inch across-flats width fits standard 1-5/16 inch hex wrenches and sockets

Compatibility

Designed as a standard 7/8-9 UNC hex nut for use with any Grade L9-rated or compatible male threaded fastener in industrial, commercial, or heavy-equipment applications requiring coarse unified thread engagement.

Installation Notes

Installation should be performed by a qualified mechanic or structural assembler using a calibrated torque wrench and appropriate 1-5/16 inch socket or open-end wrench. Isolate or de-energize the assembly before performing any fastener service on mechanical or electrical systems. Do not mix Grade L9 hardware with lower-grade fasteners in the same joint, as uneven strength ratings can compromise joint integrity. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for the specific assembly.
