Value Collection R63084640 Hex Nut 1/2-13 18-8 Ss

Product Description

The VALUE COLLECTION R63084640 is a 1/2-13 UNC hex nut machined from 18-8 stainless steel with a bright, uncoated finish. It features a right-hand thread and measures 3/4 inches across the flats with a height of 5/16 inches. The 18-8 stainless alloy provides solid corrosion resistance in wet, outdoor, and mildly chemical environments, making it a dependable fastener for general mechanical assembly. This nut is a standard field consumable used by plumbers, HVAC technicians, electricians, and general contractors wherever a 1/2-13 threaded fastener is required. Sold individually with a minimum order quantity of 100 pieces.

This hex nut is suited for light commercial and residential applications where corrosion resistance is a priority over high-strength requirements. Common installation scenarios include pipe flange connections, equipment mounting, unistrut channel assemblies, and structural bracketing in mechanical rooms. The 1/2-13 UNC thread pitch is one of the most widely used coarse-thread sizes in North American trade work, ensuring broad compatibility with standard 1/2-13 threaded rod, bolts, and studs found in plumbing, HVAC, and electrical support systems.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• 1/2-13 UNC coarse thread for compatibility with standard North American threaded fasteners
• Right-hand thread direction for conventional wrench installation
• Bright, uncoated finish — no coating to flake or interfere with thread fit
• 3/4-inch width across flats fits standard 3/4-inch open-end or socket wrenches
• Does not meet military specifications — intended for commercial and trade use

Compatibility

Designed for use with any 1/2-13 UNC threaded bolt, stud, or threaded rod requiring a standard hex nut in 18-8 stainless steel. Suitable for general mechanical, plumbing, HVAC, and electrical support assemblies using coarse-thread 1/2-13 fastener systems.

Installation Notes

A licensed tradesperson or qualified mechanic should verify thread engagement depth meets minimum requirements for the load-bearing application before final assembly. Use a 3/4-inch open-end wrench, combination wrench, or socket to drive the nut — do not use pliers, as jaw contact can damage the flats and reduce torque accuracy. Anti-seize compound may be applied to stainless threads to prevent galling, which is common in stainless-to-stainless fastener pairings. Torque to the specification called out in the equipment or structural design documentation.
