Value Collection MP31216 Hex Nut 9/16-18 Unf Steel

Product Description

The VALUE COLLECTION MP31216 is a 9/16-18 UNF zinc-plated steel hex nut designed for right-hand threaded fastener assemblies. It measures 0.875 inches across the flats and stands 0.484 inches (31/64 inches) high. The zinc plating provides a basic corrosion-resistant barrier suitable for general industrial and mechanical applications. This nut is a standard hardware component used by plumbers, HVAC technicians, electricians, and general tradespeople wherever a 9/16-18 UNF threaded connection is required. At 0.056 pounds per unit, it is a lightweight fastener appropriate for a wide range of bolted assemblies.

This hex nut is suited for light commercial and residential mechanical assemblies that call for a UNF fine-thread fastener. Fine-thread UNF fasteners are commonly specified where higher thread engagement strength or finer torque adjustment is needed compared to standard UNC coarse-thread hardware. Typical applications include equipment mounting, pipe support systems, electrical panel work, and general mechanical assemblies in the trades.

Key Features

• 9/16-18 UNF fine-thread specification for precise thread engagement
• Right-hand thread direction — standard installation direction
• 0.875 inches across the flats for use with a standard 7/8-inch wrench
• Zinc-plated finish for basic corrosion resistance in dry or mildly humid environments
• Steel construction for reliable load-bearing in general fastener applications

Compatibility

Designed for use with any 9/16-18 UNF right-hand threaded bolt or stud in standard mechanical and trade assemblies.

Installation Notes

A licensed tradesperson or qualified mechanic should install fasteners in accordance with applicable codes and equipment manufacturer specifications. Power down or de-energize any equipment before working on fastened assemblies in electrical or HVAC applications. Use a properly sized 7/8-inch wrench or socket to avoid rounding the hex flats. Do not apply excessive torque beyond the fastener or joint specification.
