Electro Hardware EKFS2-M3-1 Clinch Captive Nut M3x0.50

Product Description

The ELECTRO HARDWARE EKFS2-M3-1 is a hex head clinch captive nut designed for permanent installation into sheet metal panels and enclosures. With an M3x0.50 thread and a minimum panel thickness of 1mm, it installs by pressing into a prepared mounting hole, where the hex head resists rotation and prevents the nut from spinning during fastener engagement. Constructed from 18-8 passivated stainless steel, it resists corrosion in both indoor and outdoor electrical enclosures. The 4.5mm mounting hole diameter and 5.5mm head diameter suit standard sheet metal fabrication workflows. Electricians and panel fabricators install this hardware during enclosure assembly or field modification work.

This clinch captive nut is suited for light-gauge sheet metal panels used in electrical enclosures, HVAC control panels, junction boxes, and equipment chassis. The M3x0.50 thread is a common metric fastener size found in control board mounting applications, sub-panel assemblies, and terminal block installations. Its passivated stainless steel construction makes it appropriate for environments where mild chemical exposure or moisture is present. It ships in a package quantity of 10, supporting both single-repair and small-batch fabrication needs.

Key Features

• M3x0.50 thread size compatible with standard metric fastener hardware
• Hex head profile resists rotation during installation and fastener torque
• 1mm minimum panel thickness suits common light-gauge sheet metal
• 18-8 passivated stainless steel construction for corrosion resistance
• 4.5mm mounting hole diameter for precise panel prep
• Package quantity of 10 supports small-batch and repair applications

Compatibility

Designed as an OEM-style replacement and general-use clinch captive nut for light-gauge sheet metal panels requiring an M3x0.50 threaded insert with a minimum panel thickness of 1mm.

Installation Notes

Installation requires a press tool or arbor press to seat the nut flush into the prepared mounting hole - do not attempt hammer installation, as it can deform the hex head and compromise retention. Verify panel thickness meets the 1mm minimum before pressing. De-energize any panel or enclosure fully before performing fastener hardware work. Follow applicable NEC guidelines for enclosure integrity when modifying electrical panel structures.
