Minerallac 40130J 5/16-18 Zinc Plated Hex Nut

Product Description

The MINERALLAC 40130J is a 5/16-18 zinc-plated hex nut designed for general fastening applications in electrical, HVAC, plumbing, and mechanical trade work. The 5/16-18 designation indicates a 5/16-inch nominal diameter with 18 threads per inch, conforming to the UNC (Unified National Coarse) thread standard. The zinc plating provides corrosion resistance suitable for indoor and light-duty outdoor installations. This nut is a standard hardware component used by electricians, HVAC technicians, plumbers, and general mechanical contractors wherever a secure threaded fastening point is required.

This hex nut is appropriate for use in residential and light commercial installations. Common applications include securing electrical enclosures, mounting brackets, equipment panels, conduit supports, and HVAC component assemblies. The 5/16-18 thread size is widely used across trade work for medium-duty fastening where a standard coarse-thread hex nut is specified.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard coarse-thread fastener systems
• Zinc plating provides corrosion resistance for indoor and light outdoor environments
• Hex drive profile accepts standard 1/2-inch wrench or socket
• Lightweight at 0.01 pounds per nut, suitable for high-quantity installations

Compatibility

Designed for use with any 5/16-18 UNC threaded bolt, stud, or threaded rod in standard trade fastening applications.

Installation Notes

Installation requires a standard 1/2-inch open-end wrench, box wrench, or socket. De-energize electrical systems and follow applicable NEC requirements before installing or adjusting fasteners on electrical enclosures or equipment. Do not over-torque, as this may strip the threads or damage mating components. Inspect threads for damage before installation to ensure a secure fit.
