Value Collection R56001362 Heavy Hex Nut 5/8-18 Unf

Product Description

The VALUE COLLECTION R56001362 is a heavy hex nut threaded to a 5/8-18 UNF specification in right-hand configuration. Manufactured from stainless steel with no coating applied, this nut provides corrosion resistance in demanding service environments. The heavy hex profile offers a larger bearing surface and greater wall thickness than a standard hex nut, making it appropriate for high-load or high-vibration fastening applications. At 1-1/16 inches across the flats and 39/64 inches in height, it fits standard heavy hex tooling. Plumbers, pipefitters, HVAC technicians, and general maintenance trades use heavy hex nuts where added clamping strength or chemical exposure resistance is required.

This nut is suited for use in residential and commercial mechanical systems, structural assemblies, and equipment mounting applications where a 5/8-18 UNF thread engagement is specified. The right-hand thread direction follows standard tightening convention. Stainless steel construction makes it a practical choice in wet, coastal, or chemically active environments where carbon steel fasteners would corrode. It is sold individually and can be paired with any 5/8-18 UNF threaded rod, bolt, or stud.

Key Features

• 5/8-18 UNF thread specification with right-hand thread direction
• Heavy hex profile — 1-1/16 inches across flats for increased wrench engagement
• 39/64 inches in height for greater thread engagement depth than a standard hex nut
• Stainless steel construction with no coating for corrosion resistance
• Sold individually with no minimum order beyond one piece

Compatibility

Designed for use with any 5/8-18 UNF threaded fastener requiring a heavy hex nut. Right-hand thread engages standard bolts, studs, and threaded rod of the same thread specification.

Installation Notes

Installation requires a standard heavy hex wrench or socket sized for 1-1/16 inches across the flats. Power down or depressurize any system before removing or replacing structural fasteners. Follow applicable mechanical or structural codes for the specific assembly. Avoid mixing stainless steel nuts with carbon steel fasteners to prevent galvanic corrosion in wet environments.
