Value Collection HNI2100LH-025BX Hex Nut 1-8 Unc Left Hand

Product Description

The VALUE COLLECTION HNI2100LH-025BX is a 1-8 UNC left-hand thread hex nut machined from Grade 2 steel with a bright, uncoated finish. It measures 1.5 inches across flats and 55/64 inches in height. Left-hand thread fasteners are used where standard right-hand threads would loosen under rotational forces or torque loads. This nut is a general-purpose fastener suited for maintenance, repair, and fabrication work across mechanical, HVAC, plumbing, and structural applications. Installers and tradespeople working with counter-rotating assemblies or specialized equipment specify this thread direction to prevent self-loosening.

This hex nut is appropriate for residential and commercial applications requiring a 1-8 UNC left-hand threaded fastener. Typical uses include securing components on rotating shafts, fan assemblies, pump housings, and other mechanical systems where torque direction would back off a standard right-hand nut. It is compatible with Grade 2 steel threaded rod, bolts, or studs using the same 1-8 UNC left-hand specification.

Key Features

• Left-hand thread direction prevents loosening in counter-rotating or reverse-torque applications
• Grade 2 steel construction provides adequate strength for general-purpose mechanical fastening
• 1-8 UNC thread standard ensures broad compatibility with matching left-hand threaded fasteners
• Bright uncoated finish — suitable for indoor or protected environments
• 1.5 inches across flats accommodates standard hex tooling

Compatibility

Designed for use with 1-8 UNC left-hand threaded bolts, studs, or threaded rod of matching Grade 2 or equivalent steel specification. Does not meet military specifications.

Installation Notes

Left-hand thread fasteners tighten counterclockwise — confirm thread direction before installation to avoid cross-threading or stripping. Power down or de-energize any rotating equipment before servicing fasteners on shafts or mechanical assemblies. Use a properly sized hex wrench or socket matching the 1.5-inch across-flats dimension. Minimum order quantity is 5 units.
