Value Collection MP31203 3/8-16 Unc Steel Hex Nut

Product Description

The VALUE COLLECTION MP31203 is a 3/8-16 UNC hex nut made from steel with a zinc clear finish. It features right-hand threading conforming to Unified National Coarse (UNC) standards. The nut measures 9/16 inches across the flats and 21/64 inches in height, making it a standard fastener suited for general mechanical and structural assembly work. Licensed tradespeople, maintenance technicians, and contractors use this nut in a wide range of bolted connections where a reliable, corrosion-resistant fastener is needed.

This hex nut is appropriate for residential, commercial, and light industrial applications. It is commonly used in HVAC equipment assembly, plumbing bracket installations, electrical panel mounting, and general mechanical fastening wherever a 3/8-16 UNC threaded bolt or stud is present. The zinc clear finish provides basic corrosion resistance for indoor and sheltered outdoor environments.

Key Features

• 3/8-16 UNC thread form for broad compatibility with standard inch-series fasteners
• Right-hand thread direction for conventional tightening
• Steel construction for reliable tensile strength in general-duty applications
• Zinc clear finish for basic corrosion resistance
• 9/16 inches across flats for use with standard 9/16-inch wrenches and sockets
• 21/64 inches height — standard hex nut profile

Compatibility

Designed for use with any 3/8-16 UNC threaded bolt or stud in standard inch-series fastener applications across mechanical, structural, and trade installations.

Installation Notes

Install using a standard 9/16-inch wrench or socket. Power down or de-energize any equipment before performing fastener work on electrical or mechanical assemblies. Hand-tighten first to confirm thread engagement, then torque to the specification required by the equipment manufacturer or applicable code. Do not mix with metric fasteners — UNC threads are not interchangeable with metric thread forms.
