Value Collection 34038 Hex Lock Nut 7/16-20 Nylon Insert

Product Description

The VALUE COLLECTION 34038 is a nylon insert hex lock nut designed to resist loosening under vibration and torque. It uses a nylon collar pressed into the top of the nut to create prevailing torque, which grips the mating thread without a separate locking device. The fastener is manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The thread size is 7/16-20 UNF with a right-hand thread direction. It measures 21/64 inches in height and 11/16 inches across the flats. Licensed tradespeople and maintenance mechanics use this nut across HVAC equipment assemblies, plumbing fixtures, electrical panel brackets, and general mechanical applications.

This nut is suited for light to medium-duty fastening applications where a one-time or limited-reuse locking fastener is acceptable. It is commonly used in residential and light commercial equipment assembly, structural brackets, and serviceable mechanical connections. The UNF thread standard makes it compatible with inch-series hardware found throughout most domestic trade and manufacturing environments. It is appropriate wherever a prevailing-torque locking nut is specified on a 7/16-20 threaded fastener.

Key Features

• Nylon insert locking style provides prevailing torque without adhesive or additional hardware
• 7/16-20 UNF right-hand thread for standard inch-series compatibility
• Grade 2 steel construction for light to medium-duty load requirements
• Zinc-plated finish offers basic protection against moisture and corrosion
• Compact hex profile at 11/16 inches across flats suits standard open-end and socket wrenches

Compatibility

Designed as an OEM-style replacement or general-use nylon insert hex lock nut for 7/16-20 UNF inch-series threaded fastener applications.

Installation Notes

A licensed mechanic or journeyman tradesperson installs this nut using a standard 11/16-inch open-end or socket wrench. Power down and de-energize any equipment before servicing fastener connections on electrical or HVAC assemblies. Nylon insert lock nuts are rated for limited reuse — inspect the nylon collar for deformation before reinstalling a previously used nut. Follow applicable mechanical and equipment codes for fastener torque requirements specific to the assembly.
