Electro Hardware ECLS-0420-2 Clinch Nut 1/4-20 Ss

Product Description

The ELECTRO HARDWARE ECLS-0420-2 is a round head clinch captive nut designed for permanent installation into sheet metal and thin panel assemblies. This fastener presses into a pre-drilled mounting hole and clinches in place, creating a fixed threaded insert that accepts a 1/4-20 bolt or screw. Manufactured from 18-8 stainless steel with a passivated finish, it delivers corrosion resistance suited to demanding environments. The round head profile measures 0.44 inches in diameter and 0.17 inches in height, with a body diameter of 0.343 inches. Minimum panel thickness required for proper clinching is 0.0909 inches.

This clinch nut is suited for use in electrical enclosures, control panels, HVAC equipment housings, and light structural assemblies where a flush or low-profile threaded anchor is needed in thin-gauge sheet metal. The passivated stainless steel construction makes it appropriate for applications with exposure to moisture or corrosive environments. Installation is typically performed during fabrication or panel assembly before final equipment build-out. The 1/4-20 thread size is a common fastener standard across electrical, HVAC, and mechanical panel applications.

Compatibility

Designed as a standard press-in clinch captive nut for thin sheet metal panels with a minimum thickness of 0.0909 inches and a 0.344 inch mounting hole diameter accepting 1/4-20 fasteners.

Installation Notes

Clinch nuts are installed by pressing the body into the pre-drilled panel hole using an arbor press or appropriate press tooling until the head seats flush against the panel surface. Power down and de-energize any assembly before installing fasteners into live electrical enclosures. Verify panel thickness meets the 0.0909 inch minimum before pressing to ensure proper clinch retention. Do not install with impact tools, as this can deform the head or distort thread engagement.
