Value Collection MPC712212 Hex Lock Nut 5/8-11 Unc Grade B

Product Description

The VALUE COLLECTION MPC712212 is a 5/8-11 UNC Grade B hex lock nut with a distorted thread locking mechanism, finished in zinc and wax plating. Distorted thread lock nuts resist loosening under vibration and torque by deforming slightly against the mating fastener thread, creating mechanical resistance without requiring a separate locking insert. The zinc and wax plated finish provides basic corrosion resistance and reduces galling during installation. This nut is used by plumbers, HVAC technicians, electricians, and general mechanical trades wherever a reliable threaded fastener is required in light to medium-duty applications.

The MPC712212 suits installations where a 5/8-11 UNC thread pattern is specified. It is appropriate for use in mechanical assemblies, equipment mounting, pipe support hardware, and structural bracketing across residential and light commercial settings. Sold in a package of 10, this nut is well suited for contractors who need a small quantity on hand for service calls or repair work rather than bulk stocking.

Key Features

• Distorted thread design creates mechanical locking action without adhesive or insert
• Grade B steel construction for standard-duty fastening applications
• 5/8-11 UNC thread size for wide compatibility with common fastener hardware
• Zinc and wax plated finish for corrosion resistance and reduced installation friction
• Packaged in quantities of 10 to suit service and repair use

Compatibility

Designed as an OEM-style replacement or service fastener for any assembly using a 5/8-11 UNC threaded bolt or stud requiring a locking hex nut.

Installation Notes

Installation is performed with a standard hex wrench or socket set. Ensure mating bolt threads are clean and free of damage before installation to preserve the distorted thread locking function. Do not reuse distorted thread lock nuts after removal, as the locking interference is reduced once the nut has been torqued. Follow applicable mechanical or equipment codes for proper fastener torque class and plating requirements in your specific application.
