Value Collection HNI5050LH-100BX Hex Nut 1/2-13 Lh Grade 2

Product Description

The VALUE COLLECTION HNI5050LH-100BX is a 1/2-13 left-hand thread hex nut manufactured from Grade 2 steel with a bright, uncoated finish. Left-hand thread fasteners rotate counterclockwise to tighten, making them the correct choice for applications where standard right-hand threads would loosen under operational torque or rotation. This nut measures 0.75 inches across flats and 7/16 inches in height, conforming to UNC thread standards. It is used by mechanical contractors, HVAC technicians, plumbers, and general trade professionals wherever a left-hand threaded connection is required to maintain joint integrity.

This hex nut is suited for mechanical, industrial, and trade applications that specifically require left-hand thread fasteners — such as rotating shafts, fan assemblies, pedal and linkage hardware, and other components subject to rotational forces that would back off a standard right-hand nut. The bright, uncoated steel finish is appropriate for dry or controlled-environment installations. This listing is sold as a box of 100 nuts, making it practical for shop stock, service trucks, or project-quantity needs.

Key Features

• Left-hand thread orientation prevents loosening in counterclockwise-rotation applications
• 1/2-13 UNC thread size — a widely used coarse-thread standard in trade and industrial work
• Grade 2 steel construction offers standard tensile strength for general-duty fastening
• Bright, uncoated finish — no plating or coating that could affect thread tolerance
• 0.75 inches across flats for use with standard 3/4-inch hex wrench or socket
• Sold in a 100-count quantity for job-site or shop-stock convenience

Compatibility

Designed for use in any assembly requiring a 1/2-13 UNC left-hand thread hex nut in Grade 2 steel. Verify thread direction before installation — left-hand thread fasteners are not interchangeable with standard right-hand thread hardware.

Installation Notes

Left-hand thread nuts tighten counterclockwise and loosen clockwise — confirm thread direction before applying torque to avoid cross-threading or joint failure. Always de-energize, lock out, and tag out any equipment before accessing rotating assemblies or mechanical fastener points. Use a properly sized 3/4-inch hex wrench or socket to seat the nut without rounding the flats. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque and joint specification.
