Value Collection R50000114 Hex Lock Nut 1-1/8-7 Unc

Product Description

The VALUE COLLECTION R50000114 is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade B steel with a zinc finish for corrosion resistance, this nut features a 1-1/8-7 UNC thread size with right-hand thread direction. The nylon insert collar deforms around the mating thread, creating a prevailing torque that holds the nut in place without requiring additional locking hardware. It measures 1-11/64 inches in height and 1-5/8 inches across the flats. Technicians and tradespeople working with structural fastening applications rely on this type of hardware for secure, reliable connections in mechanical and industrial assemblies.

This hex lock nut is suited for general mechanical, HVAC, plumbing support, and electrical enclosure assembly applications where vibration resistance is required. It follows inch measurement standards and carries a UNC thread form, making it compatible with standard inch-series bolts and threaded rod in residential and light commercial construction and equipment installation.

Key Features

• Nylon insert locking style provides vibration-resistant prevailing torque without secondary locking hardware
• 1-1/8-7 UNC thread size with right-hand thread direction for standard inch-series fastener compatibility
• Grade B steel construction for reliable mechanical strength in typical fastening applications
• Zinc finish provides corrosion resistance for general indoor and light-duty outdoor use
• Height of 1-11/64 inches and width across flats of 1-5/8 inches for use with standard hex tooling
• Width across points of approximately 1.826 inches for clearance planning

Compatibility

Designed for use with standard 1-1/8-7 UNC inch-series threaded bolts and threaded rod in general mechanical and structural fastening applications.

Installation Notes

Install using a standard hex wrench or socket sized to the 1-5/8-inch across-flats dimension. Hand-start the nut onto the mating thread before applying torque to avoid cross-threading. The nylon insert is a single-use locking element and should not be reused once removed from a fully engaged fastener, as the insert loses prevailing torque capacity after the first installation cycle. Ensure the mating fastener thread class and material are appropriate for the load and environmental conditions of the application.
