Value Collection R52001301 Hex Nut 7/8-14 Grade 2

Product Description

The VALUE COLLECTION R52001301 is a zinc-plated steel hex nut designed for threaded fastening applications across industrial, mechanical, and trade assembly work. Manufactured to SAE J995 Grade 2 and conforming to ANSI ASME B18.2.2 dimensional standards, this nut provides reliable clamping force for general-purpose bolted connections. It features a 7/8-14 thread size with a right-hand thread direction and a unified national (UN) thread standard. The zinc plating provides baseline corrosion resistance for indoor and protected outdoor environments. Weighing approximately 0.107 pounds per unit, it is handled and installed by mechanics, millwrights, pipefitters, and general tradespeople working with standard inch-series fastener hardware.

This hex nut is suited for general mechanical and structural assembly where a fine-thread 7/8-inch fastener is specified. Fine-thread configurations offer improved thread engagement and are commonly selected in applications requiring vibration resistance or where precise torque control is needed. Typical use cases include machine assembly, bracket mounting, and equipment maintenance across commercial and industrial settings. The zinc finish makes it appropriate for dry or mildly humid service conditions. This nut is sold individually but requires a minimum order of 10 units.

Key Features

• 7/8-14 fine-thread, right-hand, UN thread standard
• SAE J995 Grade 2 steel construction with ANSI ASME B18.2.2 conformance
• Zinc-plated finish for baseline corrosion resistance
• 1-5/16 inches (1.3125 inches) across flats for standard wrench fit
• Height of 31/64 inches (0.4844 inches) for compact stack height
• Hardness rated at 32 HRC

Compatibility

Designed as a standard replacement or maintenance hex nut for any application specifying a 7/8-14 UN fine-thread inch-series nut conforming to ANSI ASME B18.2.2 dimensional requirements.

Installation Notes

Installation is performed by hand-threading onto a compatible 7/8-14 bolt or threaded stud, then torqued to specification using a wrench sized for a 1-5/16-inch across-flats hex. Always de-energize or depressurize the assembly before servicing fastened connections on mechanical or pressurized systems. Do not substitute this Grade 2 nut where a higher-grade fastener is specified by the original equipment manufacturer or structural engineer. Ensure mating threads are clean and free of damage before assembly.
