Value Collection R50000375 High Hex Nut 5/8-18 Unf

Product Description

The VALUE COLLECTION R50000375 is a high hex nut machined from steel, designed for 5/8-18 UNF (Unified National Fine) threaded fastener applications. High hex nuts offer greater thread engagement than standard hex nuts, providing additional clamping strength in assemblies where vibration or load cycling is a concern. The right-hand thread direction is the conventional standard for most mechanical and structural fastening work. At 15/16 inches across the flats and 27/32 inches in height, this nut fits standard 5/8-inch UNF bolt and stud configurations. The uncoated finish suits applications where post-installation coating or plating is applied by the installer or end user.

This high hex nut is suitable for use in mechanical, structural, and industrial assemblies requiring a fine-thread fastener. Fine-thread UNF fasteners are commonly specified where greater tensile strength per thread is needed, where precise adjustment is required, or where thinner-walled components limit the number of available thread engagements. Typical installation scenarios include equipment brackets, machinery frames, plumbing support hardware, and HVAC structural assemblies. Sold individually with a minimum order quantity of 50 pieces.

Key Features

• High hex profile provides greater thread engagement depth than standard hex nuts
• 5/8-18 UNF thread for fine-pitch fastening applications
• Right-hand thread direction, the standard for general mechanical assembly
• 15/16 inches across flats for use with standard 5/16-inch drive or wrench tooling
• Uncoated steel construction suitable for secondary finishing or bare use
• Minimum order quantity of 50 pieces per order

Compatibility

Designed for use with 5/8-18 UNF threaded bolts, studs, and rods in right-hand thread configurations. Compatible with standard SAE and UNF fastener tooling sized for 15/16-inch across-flats hex geometry.

Installation Notes

Installation is performed with a standard 15/16-inch open-end, box-end, or socket wrench. Ensure mating bolt or stud threads are clean and free of debris before assembly. Do not mix with coarse-thread UNC hardware, as thread pitch is not interchangeable. Follow applicable torque guidelines from the equipment manufacturer or relevant industry standards for the specific assembly.
