Value Collection R63223442 Hex Lock Nut Nylon Insert 18-8 Ss

Product Description

The VALUE COLLECTION R63223442 is a hex lock nut with a nylon insert locking mechanism, manufactured from 18-8 stainless steel for corrosion resistance in demanding environments. It measures 1/4 inch in height with a 3/8-inch width across flats and features a right-hand UNF thread direction. The nylon insert deforms around mating threads to resist loosening from vibration, torque, or thermal cycling. This fastener is installed by mechanical contractors, maintenance technicians, and industrial assemblers wherever a reliable, tamper-resistant threaded connection is required in corrosive or high-vibration conditions.

This hex lock nut is suited for use in HVAC equipment assemblies, plumbing fixture mounting, electrical enclosure hardware, and general mechanical applications where stainless steel corrosion resistance and positive thread retention are required. The UNF thread standard makes it compatible with fine-thread fastener assemblies commonly found in precision mechanical and sheet metal applications. It is intended for use in inch-measurement systems and does not meet military fastener specifications.

Key Features

• Nylon insert locking style resists loosening under vibration and thermal cycling without damaging mating threads
• 18-8 stainless steel construction provides corrosion resistance in wet, humid, and chemical-exposure environments
• 1/4 inch height and 3/8 inch width across flats for compact installation in tight clearances
• Right-hand UNF thread direction conforms to inch-standard fine-thread fastener assemblies
• Does not meet military specifications — suited for commercial and industrial applications

Compatibility

Designed as an OEM-style replacement or standard component for UNF inch-series threaded assemblies requiring a nylon insert hex lock nut in 18-8 stainless steel.

Installation Notes

Install using a standard open-end or box wrench sized for 3/8 inch across flats. Nylon insert lock nuts are single-use by design — once fully torqued and removed, the insert may not provide rated locking force if reused. Ensure the mating bolt thread class and diameter are confirmed before installation. De-energize or depressurize any system before replacing fasteners on pressurized or live electrical components.
