Value Collection 99790 Hex Nut 1-1/8-7 Unc Steel

Product Description

The VALUE COLLECTION 99790 is a 1-1/8 - 7 UNC hex nut machined from steel and finished in black oxide. It features a right-hand thread direction and is sized at 1-11/16 inches across the flats with a height of 31/32 inches. Black oxide finish provides a degree of corrosion resistance and reduces light reflection on the fastener surface. This nut is a standard hardware component used in mechanical assembly, structural connections, and equipment fabrication by maintenance professionals, pipefitters, millwrights, and general tradespeople working with heavy fasteners.

The 99790 suits applications requiring a large-diameter, coarse-thread hex nut in steel construction. It is appropriate for bolted connections in industrial equipment, structural steel work, heavy machinery mounting, and similar mechanical assemblies where a 1-1/8 - 7 UNC thread specification is called out. Sold individually with a minimum order quantity of 10 pieces per order.

Key Features

• 1-1/8 - 7 UNC coarse thread form for high-clamping-load applications
• Right-hand thread direction — standard installation direction
• Steel construction for strength in structural and mechanical assemblies
• Black oxide finish reduces surface corrosion and minimizes light reflection
• 1-11/16 inches across flats for use with standard heavy hex wrenches and sockets
• 31/32 inches tall — full hex nut height for maximum thread engagement

Compatibility

Designed for use with 1-1/8 - 7 UNC threaded fasteners and bolts in steel structural, industrial, and mechanical assembly applications.

Installation Notes

Installation is performed by qualified tradespeople using a correctly sized hex socket or open-end wrench matching the 1-11/16-inch across-flats dimension. Ensure mating bolt threads are clean, undamaged, and of the same UNC thread standard before installation. Consult applicable torque specifications from the equipment manufacturer or relevant industry standards for the specific assembly. Do not mix UNC and UNF hardware in the same fastened joint.
