Value Collection T41NTE120 Hex Lock Nut 3/4-10 Unc Grade 2

Product Description

The VALUE COLLECTION T41NTE120 is a 3/4-10 UNC Grade 2 hex lock nut with a nylon insert, designed to maintain thread engagement under vibration and dynamic loading. Constructed from steel with a zinc-plated finish for basic corrosion resistance, this fastener measures 1-1/16 inches across the flats and 13/32 inches in height. The nylon insert deforms around mating threads to create a prevailing torque that resists loosening without requiring a secondary locking device. It is installed by maintenance technicians, electricians, plumbers, HVAC mechanics, and general tradespeople wherever a reliable, reusable locking fastener is required.

This hex lock nut is suited for a wide range of light- to medium-duty fastening applications in residential, commercial, and light industrial settings. Common uses include equipment mounting, pipe and conduit support bracketing, and mechanical assemblies where vibration or intermittent loading would otherwise back off a standard hex nut. The 3/4-10 UNC thread form is one of the most common coarse-thread sizes in North American trade work, making this nut broadly applicable across plumbing, HVAC, electrical, and general mechanical installations.

Key Features

• Nylon insert creates prevailing torque to resist vibration-induced loosening
• 3/4-10 UNC coarse thread for broad compatibility with standard fastener stock
• Grade 2 steel construction for light- to medium-duty load applications
• Zinc-plated finish provides basic corrosion protection in dry to mildly humid environments
• 1-1/16 inch width across flats fits standard combination wrenches and sockets

Compatibility

Designed as a standard replacement or stocking fastener for any 3/4-10 UNC threaded bolt or stud requiring a prevailing-torque locking nut.

Installation Notes

Installation requires a standard 1-1/16 inch combination wrench or socket. De-energize or shut off any associated equipment before accessing fastener points in live systems. The nylon insert allows reuse but should be inspected for wear or deformation after removal from a joint. Do not exceed the torque limits appropriate for Grade 2 steel fasteners at this thread size as referenced in applicable mechanical or structural codes.
