Value Collection L52CLC0420 Hex Lock Nut 1/4-20

Product Description

The VALUE COLLECTION L52CLC0420 is a 1/4-20 hex lock nut that uses a distorted-thread locking style to resist loosening under vibration and torque. Manufactured from Grade C steel with a clear cadmium plating, this fastener measures 7/32 inches in height and 7/16 inches across the flats. The right-hand thread follows the UNC (Unified National Coarse) standard. It is sized for use in mechanical assemblies where a reliable, reusable locking nut is required without the need for separate locking inserts or adhesives. Tradespeople across HVAC, plumbing, and general mechanical work routinely specify this nut type for panel, bracket, and equipment fastening applications.

This hex lock nut is suited for light-duty to medium-duty fastening applications in residential and commercial mechanical systems. The distorted-thread design provides consistent prevailing torque without added hardware, making it practical for assemblies that may require periodic disassembly. The clear cadmium finish provides corrosion resistance in mild environments. Licensed tradespeople and fabricators typically use this nut where UNC threaded bolts or studs are already in place.

Key Features

• Distorted-thread locking style resists loosening without secondary locking elements
• 1/4-20 UNC right-hand thread for compatibility with standard inch-system fasteners
• Grade C steel construction for reliable mechanical strength
• Clear cadmium plating provides corrosion resistance in mild-duty environments
• 7/16-inch width across flats accepts standard hex drive tools
• Low profile at 7/32 inches high for use in space-constrained assemblies

Compatibility

Designed for use with 1/4-20 UNC threaded bolts and studs following inch-system fastener standards in general mechanical, HVAC, plumbing, and electrical enclosure applications.

Installation Notes

Installation should be performed by qualified tradespeople using an appropriately sized hex wrench or socket. Power down or de-energize any equipment before fastening hardware near electrical components. Do not reuse distorted-thread lock nuts in critical load-bearing joints if the prevailing torque has been noticeably reduced from prior use. Follow applicable equipment manufacturer guidelines and relevant codes for fastener torque and assembly procedures.
