Value Collection MP34288 3/4-16 Unf Hex Lock Nut Grade B

Product Description

The VALUE COLLECTION MP34288 is a 3/4-16 UNF Grade B hex lock nut with a nylon insert, designed to resist loosening under vibration and dynamic loads. Constructed from steel with a zinc-plated finish, it provides corrosion resistance suited for general mechanical and structural fastening applications. The nylon insert creates a prevailing-torque locking action without damaging mating threads. The nut measures 1-1/16 inches across the flats and stands 7/8 inches high. This fastener is installed by licensed mechanics, millwrights, pipefitters, and general tradespeople wherever a reliable, reusable locking nut is required.

This hex lock nut is used in a wide range of residential, commercial, and light industrial applications. It is well suited for equipment assembly, bracket mounting, pipe hangers, structural connections, and any threaded assembly using 3/4-16 UNF fasteners where vibration resistance is a priority. The zinc-plated finish makes it appropriate for interior and mildly corrosive environments. It conforms to Grade B dimensional standards for hex lock nuts with nylon inserts.

Key Features

• 3/4-16 UNF thread for fine-thread applications requiring precise clamping
• Grade B classification meeting standard dimensional tolerances for hex lock nuts
• Nylon insert provides prevailing-torque locking action without damaging mating threads
• Steel construction with zinc-plated finish for corrosion resistance
• 1-1/16 inch width across flats fits standard hex wrenches and sockets
• Reusable design allows disassembly and reassembly without replacing the locking element under normal service conditions

Compatibility

Designed as a standard replacement or assembly hex lock nut for any 3/4-16 UNF threaded fastener application requiring a Grade B nylon-insert prevailing-torque nut.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized to 1-1/16 inches across the flats. De-energize and lock out any equipment before servicing fasteners in live mechanical or electrical assemblies. Do not reuse nylon-insert lock nuts in high-cycle or safety-critical joints where the nylon locking element may have been degraded. Follow applicable mechanical and structural codes for fastener torque requirements based on grade, size, and joint type.
