Value Collection 1-N-37F Hex Lock Nut 3/8-24 18-8 Ss

Product Description

The VALUE COLLECTION 1-N-37F is a 3/8-24 UNF hex lock nut with a nylon insert locking mechanism, manufactured from 18-8 stainless steel with a bright uncoated finish. The nylon insert compresses against the bolt threads when the nut is driven home, creating friction-based resistance to vibration-induced loosening without damaging the mating threads. At 29/64 inches tall with a 9/16-inch width across flats, this fastener fits standard 9/16-inch open-end and box wrenches. Suitable for mechanical assemblies in corrosive or moisture-prone environments where stainless material is specified. HVAC, plumbing, and equipment-mounting applications commonly call for this thread size and material grade.

This nut is used in light to medium mechanical assemblies requiring vibration resistance and corrosion protection. The 3/8-24 UNF fine thread pitch provides stronger thread engagement per inch than coarse thread equivalents, making it a common choice in HVAC equipment brackets, pump mounting hardware, and electrical enclosure hardware where stainless fasteners are required by spec or environment. Right-hand thread direction is standard for conventional installation. Minimum order quantity is 100 pieces.

Key Features

• Nylon insert locking style resists vibration loosening without thread damage
• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• 3/8-24 UNF fine thread for increased thread engagement strength
• Right-hand thread direction for standard installation with conventional tooling
• Bright uncoated finish — no coating delamination risk in high-humidity service
• Width across flats of 9/16 inches fits standard open-end, box, and socket wrenches

Compatibility

Designed for use with 3/8-24 UNF right-hand thread fastener assemblies requiring a nylon insert hex lock nut in 18-8 stainless steel.

Installation Notes

Installation requires a 9/16-inch wrench or socket. Power down or de-energize any equipment before servicing fastened assemblies on electrical or HVAC components. Drive the nut to the specified clamping torque for the 3/8-24 thread size and stainless steel material grade per the applicable mechanical or equipment specification — do not rely on nylon insert drag alone as a torque indicator. Nylon insert lock nuts are generally considered single-use; replace the nut if it has been fully threaded off a fastener and reuse is not approved by your assembly spec.
