Electro Hardware EKF2-M4-1.5-ZI M4x0.70 Broach Captive Nut

Product Description

The ELECTRO HARDWARE EKF2-M4-1.5-ZI is an M4x0.70 round head broach captive nut designed for permanent installation into sheet metal panels and enclosures. The broach installation method presses the nut into a punched or drilled hole, creating a flush, vibration-resistant threaded insert without welding or adhesives. The zinc plated steel construction provides corrosion resistance suitable for indoor industrial and electrical enclosure applications. This fastener requires a minimum panel thickness of 1.5 mm and accepts a 6.4 mm mounting hole diameter. It is typically installed by fabricators, electricians, and panel builders working with light-gauge steel or aluminum enclosures.

This captive nut is suited for use in electrical control panels, HVAC equipment housings, server rack assemblies, and general sheet metal fabrication where a reliable internal thread is needed in thin-panel applications. The round head profile sits flush or near-flush after installation, keeping interior panel surfaces clear of sharp protrusions. Sold in a package quantity of 25 with a minimum order quantity of 1 package.

Compatibility

Designed as a standard broach-style captive nut for light-gauge sheet metal panels and enclosures requiring an M4x0.70 threaded insert with a minimum panel thickness of 1.5 mm.

Installation Notes

Installation requires a properly sized 6.4 mm mounting hole drilled or punched in the panel before pressing the nut into place. A press tool or arbor press is recommended to seat the broach nut fully without damaging the panel or thread. Ensure the panel is de-energized and secure before performing any fastener installation on live electrical enclosures. Follow applicable NEC guidelines when working inside energized panel environments.
