Value Collection L52CLC1409 Hex Lock Nut 7/8-9

Product Description

The VALUE COLLECTION L52CLC1409 is a 7/8-9 UNC distorted-thread hex lock nut manufactured from Grade C steel with a clear cadmium finish. Distorted-thread locking nuts resist loosening under vibration and dynamic loads by deforming a portion of the thread profile, which creates a prevailing torque when the nut is driven onto the fastener. This eliminates the need for a separate locking element such as a split washer or thread-locking compound. At 49/64 inches high with a 1-5/16-inch width across flats, this nut fits standard 7/8-9 UNC bolts and studs commonly found in mechanical, HVAC, and industrial assemblies.

This hex lock nut is suited for residential and commercial mechanical assemblies where vibration resistance is required without secondary locking hardware. Typical applications include equipment mounting brackets, structural connections, and general trade installations where a standard 7/8-9 UNC fastener is specified. The clear cadmium finish provides a degree of corrosion resistance for light-duty service environments. The right-hand thread direction conforms to standard UNC practice, making this a straightforward drop-in fastener for most field and shop applications.

Key Features

• Distorted-thread design creates prevailing torque without secondary locking hardware
• 7/8-9 UNC right-hand thread for compatibility with standard inch-series bolts and studs
• Grade C steel construction for reliable mechanical strength in general-purpose use
• Clear cadmium finish offers light corrosion resistance
• 1-5/16 inches across flats fits standard 7/8-inch hex wrench or socket
• Conforms to inch measurement system per UNC fastener standards

Compatibility

Designed as a standard UNC replacement or service hex lock nut for 7/8-9 inch-series threaded fastener applications in mechanical, industrial, and trade service assemblies.

Installation Notes

Install using a standard 1-5/16-inch hex wrench or socket. De-energize and lock out any equipment before performing fastener service on live mechanical or electrical assemblies, following applicable OSHA lockout/tagout procedures. Distorted-thread lock nuts are generally considered single-use; replace with a new nut if the prevailing torque is noticeably reduced after removal. Do not use thread-locking compounds with distorted-thread nuts, as this may interfere with the designed locking mechanism.
