Electro Hardware EWN-024-0 Cu Round Head Steel Weld Nut

Product Description

The ELECTRO HARDWARE EWN-024-0 CU is a round head steel weld nut designed for permanent attachment to sheet metal panels and fabricated assemblies. It features a 10-24 inch thread and a body diameter of 0.44 inches, making it suitable for light-gauge steel panels with a minimum thickness of 0.03 inches. The copper flash finish provides a thin layer of corrosion resistance and aids weld conductivity. Three projections locate and secure the nut during the resistance welding process before a permanent weld bead is formed. This fastener is specified by fabricators, HVAC sheet metal workers, electricians, and assembly technicians who need a flush, captive threaded insert welded directly into a panel.

This weld nut is used in residential and commercial applications where a threaded attachment point must be permanently fixed to thin sheet metal without access to the back side of the panel. Typical install scenarios include HVAC cabinet assembly, electrical enclosure fabrication, and general sheet metal work where a bolt or machine screw must thread into a panel from one side. The 0.25-inch pilot hole diameter and 0.155-inch pilot height allow the nut to self-locate in a punched hole before welding. This item is sold in a package quantity of 25.

Key Features

• 10-24 inch thread size for standard machine screw compatibility
• Round head profile with three projections for consistent resistance welding
• 0.44-inch body diameter fits standard punched pilot holes of 0.25 inches
• 0.155-inch pilot height locates the nut securely before welding
• Copper flash finish aids weld conductivity and provides light corrosion protection
• Minimum panel thickness of 0.03 inches suits light-gauge sheet metal applications

Compatibility

Designed as an OEM-style replacement or new-installation weld nut for light-gauge sheet metal panels requiring a permanent 10-24 threaded insert in residential and commercial fabrication applications.

Installation Notes

Installation requires a resistance spot welder capable of welding projection nuts to sheet metal. Ensure the panel is clean and free of coatings at the weld site before locating the nut. Power down any associated equipment before working on energized enclosures or panels. Verify pilot hole diameter and panel thickness meet the specified minimums before welding to ensure full projection contact and a sound weld.
