Value Collection HNFI5087LH-025BX Hex Nut 7/8-14 Lh

Product Description

The VALUE COLLECTION HNFI5087LH-025BX is a 7/8-14 UNF left-hand thread hex nut manufactured from Grade 2 steel with a bright, uncoated finish. It measures 1-5/16 inches (1.3125 inches) across the flats and 3/4 inch in height. Left-hand thread fasteners are used where standard right-hand threads would loosen under rotational loads or vibration — common in rotating shafts, fan assemblies, and certain mechanical linkages. Installers in HVAC, plumbing, and mechanical trades reach for left-hand hardware specifically to counteract torque-induced loosening in those applications.

This hex nut is suited for mechanical and structural assembly work where a 7/8-14 UNF left-hand thread fastener is required. Typical applications include fan blade retention, rotating equipment, and any assembly where counterclockwise rotation would otherwise back out a standard nut. It is sold in a minimum order quantity of 5 pieces, with each package containing 1 nut.

Key Features

• Left-hand thread direction — resists loosening under counterclockwise rotation
• 7/8-14 UNF thread size for fine-thread engagement and improved holding strength
• Grade 2 steel construction provides adequate strength for general mechanical use
• Bright uncoated finish — no coating to affect thread tolerances or dimensional fit
• 1-5/16 inches across flats — fits standard 1-5/16 inch open-end or box wrench
• 3/4 inch height provides full thread engagement depth

Compatibility

Designed for use with any 7/8-14 UNF left-hand threaded bolt or stud in general mechanical, HVAC, plumbing, or industrial assembly applications.

Installation Notes

Left-hand thread fasteners tighten counterclockwise and loosen clockwise — opposite of standard hardware. A licensed mechanic or journeyman tradesperson should confirm thread direction before installation to avoid cross-threading or assembly errors. De-energize and lock out all rotating equipment before installing or removing fasteners. Use a properly sized 1-5/16 inch wrench; adjustable wrenches may round the flats on hardened fasteners.
