Value Collection 177 Hex Nut 5/8-18 18-8 Stainless Steel

Product Description

The VALUE COLLECTION 177 is a 5/8-18 UNF hex nut machined from 18-8 stainless steel with a bright, uncoated finish. It features a right-hand thread and measures 15/16 inches across the flats with a height of 35/64 inches. The 18-8 stainless alloy provides solid corrosion resistance in wet or mildly corrosive environments, making this nut a dependable choice for mechanical assemblies, HVAC equipment mounting, plumbing fixtures, and general trade fastener applications. Licensed tradespeople and experienced installers working across HVAC, plumbing, electrical, and pool service sectors use this hardware type as a standard fastening component.

This hex nut is suited for use in residential and light commercial applications wherever a 5/8-18 UNF fine-thread fastener is required. Fine-thread UNF fasteners are commonly used in applications demanding tighter thread engagement and higher resistance to loosening under vibration, such as equipment mounting brackets, pipe hangers, and panel hardware. The stainless steel construction makes it appropriate for damp or outdoor-adjacent environments where mild corrosion resistance is needed.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and mildly corrosive environments
• 5/8-18 UNF fine-thread specification for tighter engagement and vibration resistance
• Right-hand thread direction — standard installation orientation
• Bright, uncoated finish maintains dimensional accuracy and is compatible with standard wrenches
• 15/16-inch width across flats fits standard hex wrench and socket tooling

Compatibility

Designed as a standard 5/8-18 UNF hex nut replacement or new-install fastener for trade assemblies requiring 18-8 stainless steel hardware with right-hand thread orientation.

Installation Notes

Installation does not require specialized trade licensing but should follow applicable mechanical codes for the system being serviced. Power down or de-energize any equipment before accessing fastener locations on electrical or HVAC panels. Use a properly sized 15/16-inch wrench or socket to avoid rounding the flats. Do not mix stainless steel fasteners with incompatible metals in highly corrosive environments where galvanic corrosion may be a concern.
