Value Collection NLMSIX0-6NM-100BX Hex Lock Nut 18-8 Ss

Product Description

The VALUE COLLECTION NLMSIX0-6NM-100BX is a nylon insert hex lock nut manufactured from 18-8 stainless steel. It uses a nylon insert locking mechanism to resist vibration-induced loosening without requiring thread adhesives or external locking washers. The nut measures 9/64 inches in height with a width across flats of 5/16 inches, and it follows a right-hand thread direction per UNC fastener standards. This hardware is sized for use in inch-measurement fastener systems and is well suited for mechanical assemblies, HVAC brackets, plumbing support hardware, and electrical enclosure installations where corrosion resistance and positive locking are both required.

This hex lock nut is appropriate for use in light-duty to medium-duty fastening applications where stainless steel corrosion resistance is needed. Typical install environments include indoor and outdoor assemblies exposed to moisture, mild chemicals, or temperature cycling. Plumbers, HVAC technicians, and electricians encounter this style of hardware when securing mounting brackets, equipment panels, and pipe support structures. The nylon insert engages the mating threads near the top of the nut to create a prevailing-torque lock that remains effective across repeated assembly and disassembly cycles.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or chemically exposed environments
• Nylon insert locking style creates prevailing torque without adhesives or external lock washers
• Right-hand UNC thread direction compatible with standard inch-series fastener systems
• Compact profile at 9/64 inches height suits installations with limited axial clearance
• Does not meet military specifications — intended for commercial and trade applications

Compatibility

Designed as an OEM-style replacement or service stock hex lock nut for inch-measurement UNC threaded fastener assemblies in commercial and residential trade applications.

Installation Notes

This nut is installed by licensed trades and skilled technicians using standard open-end or box wrenches sized to the 5/16-inch width across flats. Power down or de-energize any equipment before accessing fastened assemblies in electrical or HVAC applications. Do not exceed the rated engagement of the nylon insert by over-torquing, as this can compromise the locking function. Follow applicable codes such as NEC or IFGC when this hardware is used in code-governed installations.
