Value Collection R63223229 Hex Lock Nut 18-8 Ss Nylon Insert

Product Description

The VALUE COLLECTION R63223229 is a hex lock nut with a nylon insert locking mechanism, manufactured from 18-8 stainless steel. The nylon insert deforms around the mating thread when driven to final position, creating resistance to loosening caused by vibration or dynamic loading. The nut measures 15/64 inches in height with a width across flats of 11/32 inches. It uses a right-hand, UNC (Unified National Coarse) thread standard. Typical installers include plumbers, HVAC technicians, electricians, and mechanical contractors who need corrosion-resistant fasteners in wet, outdoor, or chemically active environments.

This nylon insert lock nut is suited for residential and light commercial applications where stainless steel fasteners are required to resist corrosion. Common use cases include mounting hardware in HVAC equipment, plumbing brackets, electrical enclosures, and general mechanical assemblies exposed to moisture or mild chemicals. The 18-8 stainless steel grade provides good resistance to rust and oxidation without the need for a separate coating or treatment. The UNC thread pattern is standard across a wide range of hardware in inch-measurement applications.

Key Features

• Nylon insert locking style resists loosening from vibration and dynamic loads without secondary locking hardware
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Right-hand UNC thread for compatibility with standard inch-measurement fastener systems
• Compact profile: 15/64 inches high and 11/32 inches across flats
• Inch system of measurement — pairs with standard SAE bolts and threaded rod

Compatibility

Designed for use with UNC right-hand threaded fasteners in inch-measurement systems. Confirm bolt diameter and thread pitch before installation to ensure proper engagement and locking performance.

Installation Notes

Install with a standard open-end or combination wrench sized to 11/32 inches across flats. Drive the nut down until the nylon insert fully engages the mating thread — the torque increase is the indicator of proper seating. Nylon insert lock nuts are generally considered single-use; once the insert has been fully engaged and removed, locking performance may be reduced. De-energize or de-pressurize any assembly before replacing fasteners in live mechanical or electrical systems.
