Value Collection R56001366 Heavy Hex Nut 3/4-16 Unf

Product Description

The VALUE COLLECTION R56001366 is a heavy hex nut threaded to a 3/4-16 UNF right-hand specification, manufactured from stainless steel for corrosion resistance in demanding service environments. It measures 1-1/4 inches across flats and 47/64 inches in height, conforming to the heavy hex profile that provides greater bearing surface than standard hex nuts. This fastener is supplied uncoated and is suited for mechanical, plumbing, and structural assembly applications where a UNF thread form and elevated material strength are required. Licensed tradespeople and maintenance professionals working on pipework, equipment mounting, and industrial assemblies will find this nut a reliable, off-the-shelf replacement or build component.

This heavy hex nut is appropriate for use in residential and commercial mechanical systems wherever a 3/4-16 UNF threaded fastener is called for. The heavy hex profile is commonly specified in flanged connections, pressure equipment, and structural bolting situations where standard hex nuts do not provide sufficient clamp load distribution. The stainless steel construction makes it suitable for wet, corrosive, or outdoor environments where carbon steel hardware would be prone to rust or galvanic degradation.

Key Features

• 3/4-16 UNF right-hand thread for compatibility with standard fine-thread fastener systems
• Heavy hex profile at 1-1/4 inches across flats provides increased bearing surface versus standard hex
• Stainless steel construction resists corrosion in wet, outdoor, and chemically active environments
• Uncoated finish - no plating to crack, flake, or interfere with thread engagement
• 47/64 inches height suits applications requiring a low-profile heavy hex fastener
• Does not meet military specifications - intended for commercial and industrial use

Compatibility

Designed as an OEM-style replacement or build-spec fastener for any assembly requiring a 3/4-16 UNF right-hand heavy hex nut in stainless steel.

Installation Notes

Installation of heavy hex nuts is typically performed by licensed plumbers, pipefitters, millwrights, or mechanical contractors depending on the application. Always de-energize equipment and relieve system pressure before replacing fasteners in pressurized assemblies. Use a calibrated torque wrench and follow the fastener or equipment manufacturer torque specifications for the bolted joint. Inspect mating threads for damage or contamination before assembly to ensure proper thread engagement and clamp load.
