Value Collection HNI2075LH-025BX Hex Nut 3/4-10 Lh Grade 2

Product Description

The VALUE COLLECTION HNI2075LH-025BX is a 3/4-10 UNC left-hand-thread hex nut manufactured from Grade 2 steel with a bright, uncoated finish. Left-hand threading requires counterclockwise installation and is used wherever reverse-thread fastening is required to resist loosening under rotational forces. The nut measures 1.125 inches across flats and 41/64 inches in height. This package contains 25 nuts, making it a practical stocking quantity for shops, contractors, and maintenance crews who regularly encounter left-hand-thread applications.

Left-hand-thread hex nuts are commonly specified in mechanical and industrial assemblies where shaft rotation or vibration would otherwise back out a standard right-hand fastener. Typical applications include fan blades, grinding wheel arbors, certain bicycle components, and specialty machine assemblies. Grade 2 steel provides adequate strength for general-purpose, non-structural fastening in both indoor and light-duty outdoor settings. Trade professionals and maintenance technicians working on equipment with reverse-thread specifications will find this nut appropriate for field and shop repairs.

Key Features

• Left-hand (LH) thread direction prevents self-loosening in counterclockwise-rotating assemblies
• 3/4-10 UNC thread size for broad compatibility with standard left-hand-thread bolts and studs
• Grade 2 steel construction suitable for general-purpose, non-critical fastening
• Bright, uncoated finish — no added coating to interfere with thread fit or torque values
• 1.125 inches across flats fits standard 1-1/8-inch open-end or box-end wrenches
• Sold in a 25-count package for efficient stocking and job-site use

Compatibility

Designed for use with 3/4-10 UNC left-hand-thread bolts, studs, and threaded rod in general mechanical and industrial assemblies requiring reverse-thread fasteners.

Installation Notes

Left-hand-thread fasteners tighten counterclockwise and loosen clockwise — opposite of standard hardware. Always confirm thread direction before installation to avoid cross-threading or fastener damage. A standard 1-1/8-inch wrench or socket is required to seat this nut. Power down or de-energize any equipment before servicing fastened assemblies, and follow applicable OSHA and equipment manufacturer lockout/tagout procedures.
