Value Collection 93632 Hex Lock Nut 1/2-20 Unf 50 Pack

Product Description

The VALUE COLLECTION 93632 is a 1/2-20 UNF hex lock nut with a nylon insert, manufactured from 18-8 stainless steel. The nylon insert creates a prevailing-torque locking action that resists vibration loosening without requiring adhesives or secondary locking hardware. The uncoated 18-8 stainless construction provides corrosion resistance suitable for wet, outdoor, and chemically exposed environments. At 0.75 inches across the flats and 0.594 inches in height, this nut fits standard 1/2-20 UNF threaded fastener assemblies. These are packaged in quantities of 50, making them practical for both service calls and small production runs. Mechanical, electrical, plumbing, and HVAC technicians commonly use this hardware in fastener assemblies where vibration resistance is required.

This hex lock nut is suited for use in residential and commercial mechanical assemblies wherever a 1/2-20 UNF thread form is specified. Typical applications include equipment mounting, bracket assemblies, and any bolted joint subject to vibration or dynamic loading. The 18-8 stainless steel grade is appropriate for installations exposed to moisture or mild corrosive conditions, including outdoor equipment, pool and spa equipment enclosures, and marine-adjacent environments. The nylon insert remains effective across a wide service temperature range for standard trade applications.

Key Features

• 1/2-20 UNF thread form for fine-thread fastener assemblies
• 18-8 stainless steel construction for corrosion resistance in wet or exposed environments
• Nylon insert provides vibration-resistant prevailing-torque locking action
• Uncoated finish — no coating buildup to affect thread fit or torque values
• 0.75 inches width across flats for use with standard hex wrenches and sockets
• Packaged in quantities of 50 for efficient stocking and job-site use

Compatibility

Designed as a standard replacement or stocking hardware item for any 1/2-20 UNF fine-thread bolted assembly requiring a prevailing-torque hex lock nut.

Installation Notes

Installation requires a standard hex wrench or socket sized for 0.75 inches across the flats. Power down or de-energize any equipment before working on fastened assemblies in electrical or HVAC applications. The nylon insert is single-use by design — once the nut has been fully torqued and removed, replace it with a new nut to maintain reliable locking performance. Follow applicable mechanical codes and equipment manufacturer torque specifications for the joint being assembled.
