Value Collection 57NFP Hex Nut 9/16-18 Un Steel

Product Description

The VALUE COLLECTION 57NFP is a 9/16-18 UN steel hex nut designed for right-hand threaded fastener applications. It measures 0.875 inches across the flats and 0.484 inches in height, with an uncoated finish. This standard hex nut is used to secure bolted assemblies across a wide range of mechanical, structural, and trade installations. Plumbers, pipefitters, HVAC technicians, electricians, and general contractors regularly use UN-thread hex nuts when assembling equipment frames, brackets, flanges, and mechanical connections. The 9/16-18 fine thread designation provides a tighter thread pitch than coarse equivalents, which improves holding strength in vibration-prone environments.

This nut suits residential and commercial applications where 9/16-18 UN fine-thread fasteners are specified. Typical install scenarios include equipment mounting, mechanical assemblies, conduit support structures, HVAC equipment frames, and plumbing fixture brackets. The uncoated steel construction makes it appropriate for interior or dry-environment use. This SKU is sold individually but requires a minimum order quantity of 25 units per order.

Key Features

• 9/16-18 UN fine-thread profile for higher clamping force in vibration-prone assemblies
• Right-hand thread direction, the standard for most mechanical fastener applications
• 0.875 inches across the flats for use with standard 7/8-inch wrench or socket
• Uncoated steel construction suited for interior mechanical and structural use
• Minimum order quantity of 25 units supports job-site bulk needs

Compatibility

Designed for use with any 9/16-18 UN right-hand threaded bolt or stud in standard mechanical, HVAC, plumbing, and electrical assembly applications.

Installation Notes

Installation is performed by hand-threading the nut onto a compatible 9/16-18 UN right-hand bolt or stud, then torquing to the fastener specification required by the assembly. Use an appropriate wrench or socket sized for 7/8 inches across the flats. Follow applicable codes such as ANSI or ASME fastener standards for the specific assembly type. Inspect threads on both the nut and the mating fastener before installation to ensure proper engagement.
