Value Collection CLNI20250-100B Hex Lock Nut 1/4-20

Product Description

The VALUE COLLECTION CLNI20250-100B is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loads without the need for a secondary locking element. Made from Grade 2 steel with a zinc-plated finish, it provides basic corrosion resistance suitable for general-purpose fastening applications. The nut measures 7/32 inches in height and 7/16 inches across the flats, fitting a standard 1/4-20 UNC thread. The distorted-thread locking style creates interference with the mating fastener, generating prevailing torque that holds the nut in place through repeated stress cycles. Electricians, plumbers, HVAC technicians, and general maintenance professionals use this type of fastener in panel assemblies, equipment enclosures, and mechanical brackets.

This hex lock nut is suited for light-duty residential and commercial applications where a reliable, low-profile locking fastener is needed on 1/4-20 threaded studs, bolts, or rods. Typical install scenarios include securing equipment brackets, electrical panel components, HVAC unit housings, and plumbing support hardware. The right-hand thread direction is standard for the vast majority of threaded fastener applications.

Key Features

• Distorted-thread locking style provides prevailing torque without additional hardware
• 1/4-20 UNC thread size with right-hand thread direction
• Grade 2 steel construction for general-purpose strength requirements
• Zinc-plated finish for basic corrosion protection
• 7/32 inches height keeps a low profile in tight assemblies
• Conforms to UNC and UNF fastener standards

Compatibility

Designed as a general-purpose replacement or stocking fastener compatible with standard 1/4-20 UNC threaded bolts, studs, and rods used across HVAC, plumbing, electrical, and light mechanical applications.

Installation Notes

Installation does not require specialized tools beyond a standard 7/16-inch wrench or socket. De-energize and lock out electrical equipment before working in panels or enclosures where fasteners are being replaced or installed. Distorted-thread lock nuts are typically single-use; reuse may reduce prevailing torque and locking effectiveness. Verify thread engagement depth meets fastener manufacturer and applicable code requirements before final torque.
