Value Collection 444020BR Hex Nut 1-8 Unc Grade L9

Product Description

The VALUE COLLECTION 444020BR is a heavy-duty Grade L9 steel hex nut designed for demanding fastening applications where high tensile strength and corrosion resistance are required. It features a 1-8 UNC (Unified National Coarse) right-hand thread and measures 1-1/2 inches across flats with a height of approximately 55/64 inches. The zinc yellow dichromate and cadmium waxed finish provides a durable protective coating suited to industrial and mechanical environments. This nut is typically installed by maintenance technicians, millwrights, and mechanical contractors working on structural assemblies, machinery, or heavy equipment.

This hex nut is appropriate for use in industrial and commercial mechanical assemblies requiring a large-diameter coarse-thread fastener. It is suited for applications involving high-load bolted connections where Grade L9 material strength is specified by engineering or maintenance standards. The right-hand thread orientation is standard for the vast majority of threaded fastener applications across trades and industrial service work.

Key Features

• Grade L9 steel construction for high-strength fastening performance
• 1-8 UNC right-hand thread for compatibility with standard coarse-thread bolt assemblies
• 1-1/2 inches across flats for use with standard large hex wrenches and sockets
• Zinc yellow dichromate and cadmium waxed finish for corrosion and wear resistance
• 55/64 inch height provides full thread engagement depth on large-diameter fasteners

Compatibility

Designed as a standard 1-8 UNC hex nut for use with Grade L9 or compatible large-diameter coarse-thread bolts and studs in industrial and mechanical assembly applications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with large-diameter fastener torque requirements. Always confirm thread size, grade, and finish compatibility with the mating bolt before assembly. Use appropriately sized hex wrenches or impact sockets rated for the fastener diameter. Follow applicable torque specifications from the equipment manufacturer or engineering documentation.
