Electro Hardware EWN-632-1 Cu Round Head Steel Weld Nut 6-32

Product Description

The ELECTRO HARDWARE EWN-632-1 CU is a round head steel weld nut in a 6-32 unified coarse thread size, designed for permanent attachment to sheet metal panels and fabricated assemblies. The nut features three projections that embed into the base material during resistance welding, creating a fixed threaded insert without the need for access to the back side of the panel. With a body diameter of 0.34 inches and a pilot height of 0.093 inches, this nut locates precisely in the pilot hole before welding. A copper flash finish provides baseline corrosion resistance and promotes consistent weld conductivity. This fastener is used in light manufacturing, enclosure fabrication, and equipment assembly by sheet metal fabricators and mechanical assembly technicians.

This weld nut is suited for thin-gauge steel panels and enclosures where a captive threaded insert is required and back-side access is limited or not possible. The minimum panel thickness requirement of 0.06 inches makes it appropriate for light-gauge sheet metal commonly found in electrical enclosures, HVAC equipment cabinets, and control panel housings. The pilot hole diameter of 0.193 inches allows the nut to seat positively before the weld cycle. Each package contains 25 pieces, with a minimum order quantity of 1 package.

Key Features

• 6-32 unified coarse thread for standard machine screw fastening
• Round head profile with three projections for secure resistance welding
• Body diameter of 0.34 inches seats in a 0.193-inch pilot hole
• Pilot height of 0.093 inches aids alignment and weld positioning
• Copper flash finish supports weld conductivity and provides light corrosion resistance
• Compatible with panels as thin as 0.06 inches

Compatibility

Designed as an OEM-style weld nut for light-gauge steel sheet metal panels and fabricated enclosures requiring a permanent 6-32 threaded insert.

Installation Notes

Installation requires a resistance spot welder set up for projection welding. The base panel must have a pilot hole of 0.193 inches drilled or punched before the nut is seated. Ensure the panel is clean and free of coatings at the weld site to promote consistent weld quality. De-energize any associated equipment and follow applicable electrical safety procedures before working on panels installed in service.
