Value Collection HNI2150LH-005BX Hex Nut 1-1/2-6 Unc

Product Description

The VALUE COLLECTION HNI2150LH-005BX is a heavy hex nut with a left-hand thread configuration, designed for 1-1/2-6 UNC threaded fastener assemblies. Manufactured from Grade 2 steel with a bright, uncoated finish, this nut is suited for general-purpose mechanical and structural applications where a standard right-hand thread is not appropriate or where counter-rotation resistance is required. At 2.25 inches across flats and 1-9/32 inches in height, it is sized for use with large-diameter bolts and studs. Weighing approximately 1 pound, it is a solid, full-body nut appropriate for demanding load-bearing connections.

Left-hand thread hex nuts are typically used in applications where shaft or assembly rotation would otherwise loosen a standard right-hand nut, such as certain machinery spindles, rotating equipment, and specialty mechanical assemblies. This part is installed by machinists, millwrights, and maintenance mechanics working on industrial equipment, conveyor systems, or fabrication projects requiring non-standard thread direction. It is also used in aftermarket and specialty fastener replacements across manufacturing and general trade applications.

Key Features

• Left-hand UNC thread direction prevents loosening under specific rotational loads
• Grade 2 steel construction provides adequate strength for general mechanical use
• Bright, uncoated finish suits dry or controlled-environment applications
• 2.25 inches across flats accommodates standard large-hex wrench and socket tooling
• 1-1/2-6 UNC thread size matches heavy-duty bolt and stud stock
• Single-piece packaging allows individual replacement without bulk purchasing

Compatibility

Designed as a replacement or supplemental hex nut for 1-1/2-6 UNC left-hand threaded bolt and stud assemblies in general industrial, mechanical, and fabrication applications.

Installation Notes

Installation is performed by machinists or maintenance mechanics using an appropriately sized wrench or socket. Confirm the mating bolt or stud carries a matching left-hand thread before installation, as left-hand and right-hand hardware cannot be interchanged. De-energize and lock out any equipment before accessing threaded fastener assemblies on machinery. Apply thread lubricant or anti-seize compound per assembly specifications when working in high-temperature or corrosive environments.
