Value Collection L79NE0813 Hex Lock Nut 1/2-13 Ss

Product Description

The VALUE COLLECTION L79NE0813 is a 1/2-13 hex lock nut with a nylon insert locking mechanism, manufactured from grade 18-8 stainless steel. The nylon insert creates interference with mating threads to resist loosening caused by vibration and dynamic loads, making it suitable for mechanical assemblies where fastener retention is critical. At 39/64 inches in height with a 3/4-inch width across flats, this nut follows UNC thread standards with a right-hand thread direction. Plumbers, electricians, HVAC technicians, and general maintenance trades use this style of fastener in corrosion-prone or outdoor environments where stainless steel is specified.

This nylon insert lock nut is appropriate for residential and commercial applications where vibration resistance and corrosion resistance are both required. Common installation scenarios include equipment mounting, pipe support hardware, electrical panel work, and mechanical system assemblies. The UNC 1/2-13 thread pattern is one of the most widely used coarse-thread sizes in trade work, making this nut compatible with standard 1/2-13 bolts and threaded rod in inch-measurement systems.

Key Features

• Nylon insert locking style resists loosening under vibration without deforming the mating threads
• Grade 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• 1/2-13 UNC right-hand thread for compatibility with standard coarse-thread fasteners
• Height of 39/64 inches and 3/4-inch width across flats fit standard hex wrenches and sockets
• Inch measurement system; does not meet military specifications

Compatibility

Designed for use with standard 1/2-13 UNC right-hand threaded bolts, screws, and threaded rod in inch-measurement fastener systems.

Installation Notes

Install with a standard 3/4-inch hex wrench or socket. Hand-thread the nut fully onto the mating fastener before applying tool torque to avoid cross-threading. The nylon insert is a single-use locking feature — once fully seated and removed, the locking effectiveness is reduced and replacement is recommended. Verify the mating fastener thread class and material compatibility before installation in safety-critical assemblies.
