Value Collection MPC712204 3/8-16 Unc Hex Lock Nut 50-pack

Product Description

The VALUE COLLECTION MPC712204 is a 3/8-16 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 by creating an interference fit as the fastener is driven onto a mating bolt or stud. The zinc and wax plating provides a base level of corrosion resistance and reduces galling during installation. These nuts are intended for general mechanical and structural assembly work performed by electricians, plumbers, HVAC technicians, and maintenance tradespeople who need a reliable, code-compliant locking fastener in standard inch thread sizes.

This nut is suited for residential and light commercial mechanical applications where vibration or dynamic loading could otherwise cause conventional fasteners to back off over time. Common installation scenarios include equipment mounting, panel work, pipe support attachment, and general structural assembly. The 3/8-16 UNC thread series is widely used across trade disciplines, making this nut a staple in service kits and maintenance inventories. Sold in a package quantity of 50, this SKU is appropriate for stock replenishment or job-lot purchasing.

Key Features

Installation Notes

Installation should be performed by a qualified tradesperson familiar with fastener torque requirements for the specific joint and material being assembled. Always verify thread engagement and confirm the mating bolt or stud is clean and undamaged before driving the lock nut. De-energize and lock out any electrical or mechanical equipment before working in close proximity to live systems. Follow applicable code requirements, including NEC guidelines where electrical equipment is involved, and consult the equipment manufacturer's specifications for proper fastener torque values.
