Value Collection HNI2087LH-025BX Hex Nut 7/8-9 Lh Grade 2

Product Description

The VALUE COLLECTION HNI2087LH-025BX is a 7/8-9 left-hand thread hex nut made from Grade 2 steel with a bright, uncoated finish. It measures 1.3125 inches (1-5/16 inches) across the flats and 0.75 inches (3/4 inch) in height. Left-hand thread fasteners tighten counterclockwise, making them the correct choice in applications where standard right-hand threads would loosen under rotational forces. Plumbers, millwrights, mechanical contractors, and general tradespeople install these nuts where left-hand thread assemblies are specified. The UNC thread standard ensures dimensional consistency with matching left-hand threaded rod, bolts, or studs.

This hex nut is suited for mechanical and structural assemblies that require left-hand thread fasteners to resist loosening caused by rotational or vibrational forces. Typical applications include rotating shaft assemblies, pedal mechanisms, turnbuckles, and other engineered connections where left-hand thread engagement is specified by the design. The Grade 2 steel construction covers general-purpose, light-to-medium-duty fastening requirements in both residential and commercial construction and maintenance contexts.

Key Features

• Left-hand (LH) thread direction — tightens counterclockwise for rotation-resistant assemblies
• 7/8-9 UNC thread size for dimensional compatibility with standard left-hand threaded hardware
• Grade 2 steel construction for general-purpose light-to-medium-duty load requirements
• Bright, uncoated finish — suitable for dry or protected indoor environments
• 1-5/16 inch (1.3125 inches) width across flats for standard 1-5/16 inch wrench engagement
• 3/4 inch height providing adequate thread engagement depth for 7/8-9 threaded fasteners

Compatibility

Designed for use with 7/8-9 UNC left-hand threaded bolts, studs, and threaded rod in general mechanical and structural assemblies requiring left-hand thread fasteners.

Installation Notes

Installation requires a 1-5/16 inch wrench or socket; note that left-hand thread nuts tighten counterclockwise and loosen clockwise — the opposite of standard fasteners. Verify thread direction on mating hardware before installation to avoid cross-threading or assembly errors. Follow applicable mechanical codes and torque specifications provided by the equipment or structure manufacturer. Inspect the mating threaded component for thread damage or contamination before assembly.
