Value Collection MPC712215 3/4-16 Unf Hex Lock Nut 10 Pack

Product Description

The VALUE COLLECTION MPC712215 is a Grade B hex lock nut designed for 3/4-16 UNF threaded fastener applications. It uses a distorted thread locking mechanism to resist loosening caused by vibration and torque, eliminating the need for a separate locking element. The nut is made from steel and finished with a zinc wax plating that provides corrosion resistance in general-duty environments. With a width across flats of 1-1/8 inches, this nut fits standard hex wrenches and sockets. It is sold in a pack of 10 units, making it a practical choice for jobs requiring multiple fasteners.

This hex lock nut is suited for general mechanical assembly, maintenance, and repair work across industrial, commercial, and trade applications. The distorted thread design provides reliable prevailing torque without adhesives or separate locking hardware. It is commonly used in HVAC equipment assemblies, structural brackets, pump mounts, electrical enclosures, and similar threaded fastening scenarios where vibration resistance is required.

Key Features

• Grade B distorted thread locking mechanism resists loosening under vibration
• 3/4-16 UNF thread specification for fine-thread fastener applications
• Steel construction for reliable strength in general-duty use
• Zinc wax plated finish provides corrosion resistance
• 1-1/8 inch width across flats fits standard hex wrenches and sockets
• Pack of 10 nuts for multi-fastener jobs

Compatibility

Designed for use with 3/4-16 UNF male threaded fasteners in general mechanical and trade assembly applications requiring a Grade B prevailing torque hex lock nut.

Installation Notes

Installation is performed by qualified mechanics or trade professionals using a standard hex wrench or socket sized to 1-1/8 inches across flats. Power down or de-energize any equipment before servicing threaded connections on mechanical assemblies. The distorted thread design is intended for single-use locking; reuse of prevailing torque lock nuts after removal is not recommended per standard fastener practice. Follow applicable equipment manufacturer torque guidelines where specified.
