Value Collection 1-THN-100F Hex Lock Nut 1-14 Unf 18-8 Ss

Product Description

The VALUE COLLECTION 1-THN-100F is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loading. Machined from 18-8 stainless steel with a bright uncoated finish, it provides reliable corrosion resistance in wet, chemical-exposure, and outdoor environments. The nylon insert collar grips the mating thread without damaging it, maintaining clamp load across repeated thermal cycles. Sized for a 1-14 UNF right-hand thread, this nut measures 35/64 inches in height and 1-7/16 inches across the flats, fitting standard hex wrenches and sockets used in mechanical, plumbing, and equipment-assembly applications.

This hex lock nut is suited for fastening assemblies in HVAC equipment frames, pump and motor mounts, pool equipment enclosures, plumbing fixture connections, and general industrial installations where stainless hardware is specified. The 1-14 UNF thread pitch is a fine-thread designation commonly found on shafting, hydraulic fittings, and precision equipment hardware. Installation is performed by mechanics, millwrights, pipefitters, and equipment technicians working on assemblies that require a prevailing-torque locking solution without adhesives or thread-locking compounds.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• Nylon insert provides prevailing-torque locking without damaging mating threads
• 1-14 UNF right-hand thread for use on fine-thread shafting and equipment hardware
• Bright uncoated finish — no coating to flake, chip, or interfere with thread engagement
• Standard hex profile at 1-7/16 inches across flats accepts common wrenches and sockets
• Sold individually — no minimum bulk purchase required

Compatibility

Designed as an OEM-style replacement or service fastener for assemblies requiring a 1-14 UNF nylon insert hex lock nut in 18-8 stainless steel.

Installation Notes

Installation is performed by hand-threading the nut onto a clean, undamaged 1-14 UNF male thread, then torquing with an appropriate hex wrench or socket. De-energize and lock out all associated equipment before servicing any fastened assembly per applicable safety procedures. Nylon insert lock nuts are intended for single-use applications — inspect the nylon collar before reuse, as repeated removal reduces prevailing-torque effectiveness. Ensure mating threads are free of burrs, debris, and incompatible coatings before installation.
