Value Collection R83920332 Hex Nut 3/4-16 Unf 18-8 Ss

Product Description

The VALUE COLLECTION R83920332 is a 3/4-16 UNF hex nut machined from 18-8 stainless steel with a bright, uncoated finish. It features a right-hand thread and measures 1.125 inches across the flats with a height of approximately 0.641 inches (41/64 inch). The 18-8 stainless steel construction provides solid corrosion resistance in wet or chemically active environments. This nut is a standard fastener used across mechanical, plumbing, HVAC, and industrial service work wherever a fine-thread, corrosion-resistant hex nut is required. Licensed tradespeople and maintenance technicians reach for this grade when mild or zinc-plated hardware is not appropriate for the environment.

This nut suits residential and commercial mechanical installations involving 3/4-inch fine-thread fastener assemblies. Common applications include pipe flanges, pump mounts, equipment brackets, and structural connections that see moisture, mild chemicals, or outdoor exposure. The fine thread pitch (16 threads per inch) provides greater holding strength and more precise torque control than a coarse-thread equivalent of the same diameter, making it a preferred choice when vibration resistance or adjustment precision matters in the assembly.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and chemically active service environments
• 3/4-16 UNF fine thread for improved holding strength and vibration resistance compared to coarse-thread equivalents
• Right-hand thread direction compatible with standard fastener assemblies
• 1.125 inches across flats fits standard 1-1/8 inch open-end and box wrenches
• Bright, uncoated finish — no plating to chip, flake, or contaminate the joint
• Does not meet military specifications — intended for commercial and industrial fastener applications

Compatibility

Designed for use with any 3/4-16 UNF right-hand threaded bolt or stud in commercial, industrial, or residential mechanical assemblies requiring 18-8 stainless steel fastener hardware.

Installation Notes

Installation is performed with a standard 1-1/8 inch open-end, box, or socket wrench. Confirm that the mating bolt or stud is also 3/4-16 UNF and is compatible with 18-8 stainless steel to avoid galvanic corrosion risk when dissimilar metals are present. De-energize or depressurize the assembly before removing or replacing fasteners on active mechanical systems. Apply an anti-seize compound rated for stainless steel if the fastener will be exposed to high heat or cyclic thermal conditions, as 18-8 stainless fasteners are prone to galling under high torque without lubrication.
