Value Collection 1-N-100C Hex Lock Nut 1-8 Unc 18-8 Ss

Product Description

The VALUE COLLECTION 1-N-100C is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loads. It features an 18-8 stainless steel hex body with an integrated nylon insert that grips the mating thread and maintains clamping force without a secondary locking device. The thread size is 1-8 UNC with a right-hand thread direction. The nut measures 1-3/64 inches in height and 1-7/16 inches across the flats. This fastener is suited for trade and industrial applications where corrosion resistance and reliable thread locking are required.

This nylon insert lock nut is used in plumbing, HVAC, electrical, and general mechanical assembly applications where stainless steel corrosion resistance is needed. It is well suited for outdoor, marine-adjacent, or wet-environment installations where carbon steel fasteners would corrode. The UNC thread form is standard across North American equipment, making this nut a common service replacement in a wide range of assemblies.

Key Features

• Nylon insert locking style resists loosening under vibration without adhesives or secondary hardware
• 18-8 stainless steel construction provides strong corrosion resistance in wet or outdoor environments
• 1-8 UNC right-hand thread for compatibility with standard inch-series fastener systems
• 1-7/16 inch width across flats fits standard hex wrench and socket tooling
• Single-piece construction with no loose components to manage during installation

Compatibility

Designed for use with 1-inch diameter UNC inch-series threaded fasteners in standard trade and industrial mechanical assemblies.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized to 1-7/16 inches across the flats. Power down or de-energize any associated equipment before working on fastened assemblies. Nylon insert lock nuts are generally considered single-use; once the nylon insert has been fully threaded, replace the nut rather than reusing it to ensure reliable locking performance. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
