Electro Hardware EKF2-M5-1.5-ZI Broach Captive Nut M5x0.80

Product Description

The ELECTRO HARDWARE EKF2-M5-1.5-ZI is a broach-style captive nut designed for permanent installation into sheet metal panels and enclosures. It features an M5x0.80 thread, a round head profile, and a zinc-plated steel body for corrosion resistance. The broach design requires a punched or drilled mounting hole; the nut is pressed into the panel and retained by the knurled body displacing material around the hole. Minimum panel thickness is 1.5mm, making it suitable for light-gauge sheet metal work. Electricians, enclosure fabricators, and mechanical assembly technicians install these fasteners during panel build or field modification work.

This captive nut is used wherever a permanent, floating, or fixed threaded insert is needed in a thin metal panel. Typical applications include electrical enclosures, HVAC equipment panels, control cabinets, and sheet metal chassis assemblies. The round head sits flush against the panel surface with a 9.53mm head diameter and 3mm head height, providing a clean finished appearance on the accessible face of the panel. The 6.9mm mounting hole diameter must be maintained for correct broaching engagement and thread integrity.

Key Features

• M5x0.80 thread for compatibility with standard metric M5 fasteners
• Broach installation method creates a permanent, torque-resistant threaded insert
• Round head profile with 9.53mm head diameter seats cleanly on panel surface
• 1.5mm minimum panel thickness suits light-gauge sheet metal enclosures
• Zinc-plated steel construction provides corrosion resistance in indoor environments
• Sold in packages of 25 with a minimum order quantity of 1 package

Compatibility

Designed for use in sheet metal panels with a minimum thickness of 1.5mm and a prepared mounting hole diameter of 6.9mm. Accepts any standard M5x0.80 threaded fastener.

Installation Notes

Broach captive nuts are typically installed using an arbor press or a calibrated hand press tool to drive the nut into the prepared panel hole. Ensure the mounting hole is deburred and meets the specified 6.9mm diameter before installation. Panel thickness must be at or above the 1.5mm minimum to achieve proper retention. Once broached, the nut is not designed for removal without damaging the panel.
