Value Collection R50000020 Hex Lock Nut 1/4-20

Product Description

The VALUE COLLECTION R50000020 is a 1/4-20 hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert compresses against the mating thread when fully seated, creating prevailing torque that resists loosening from vibration and dynamic loading. At 7/32 inches high and 7/16 inches across the flats, this is a standard UNC-thread fastener sized for general-purpose mechanical assemblies. Right-hand thread direction follows standard convention. The zinc plating provides a baseline level of corrosion resistance suitable for indoor and light-duty outdoor applications.

This hex lock nut is used in general mechanical, structural, and light industrial assemblies where a vibration-resistant fastener is required on a 1/4-20 UNC-threaded fastener. Typical applications include equipment frames, brackets, panels, and fixtures across HVAC, plumbing, electrical, and general trade work. It is installed by maintenance technicians, mechanical contractors, and service professionals working on threaded assemblies that require a secure, non-loosening connection.

Key Features

• Nylon insert locking style provides prevailing torque without secondary locking hardware
• Grade 2 steel construction for general-purpose fastening applications
• Zinc-plated finish for basic corrosion resistance
• 1/4-20 UNC right-hand thread for compatibility with standard inch-system fasteners
• Compact profile at 7/32 inches high and 7/16 inches across the flats

Compatibility

Designed as a standard inch-system hex lock nut for use with 1/4-20 UNC-threaded bolts and studs in general mechanical and trade assemblies.

Installation Notes

Installation requires a standard 7/16-inch wrench or socket. Nylon insert lock nuts are single-use by design — once fully torqued and removed, the nylon insert may be compromised and the nut should not be reused in critical applications. Ensure mating bolt threads are clean and free of debris before installation. No special tools or certifications are required for standard mechanical assembly work.
