Electro Hardware ES-0524-1 Clinch Captive Nut 5/16-24

Product Description

The ELECTRO HARDWARE ES-0524-1 is a round head clinch captive nut designed for permanent installation into sheet metal panels and thin-gauge fabricated assemblies. It accepts a 5/16-24 threaded fastener and requires a minimum panel thickness of 0.056 inches to form a secure, vibration-resistant threaded connection. The round head profile measures 0.5 inches in diameter and 0.23 inches in height. Installation is achieved by pressing the nut into a prepared mounting hole, where the clinch geometry displaces panel material to lock the nut in place. The body is zinc plated steel, providing corrosion resistance appropriate for indoor and light industrial environments. Electricians, HVAC technicians, and sheet metal fabricators rely on clinch fasteners to add strong threaded points to panels without welding or loose hardware.

The ES-0524-1 is suited for use in electrical enclosures, HVAC equipment panels, control cabinets, and light structural assemblies where a permanent, flush-mountable threaded insert is required. The 5/16-24 thread size accommodates standard UNF fasteners commonly found in equipment mounting applications. The 0.413-inch mounting hole diameter and 0.411-inch body diameter allow straightforward press-in installation with standard shop tooling. This part is packaged in quantities of 10 per package and is appropriate for both field service use and light production assembly work.

Key Features

• Round head profile with 0.5 inch head diameter provides a broad bearing surface
• Minimum panel thickness of 0.056 inches suits thin-gauge sheet metal applications
• Zinc plated steel construction offers corrosion resistance for indoor and light industrial use
• Packaged in quantities of 10 per package for convenient stocking and field use

Compatibility

Designed as an OEM-style clinch captive nut for sheet metal panels requiring a 0.413-inch mounting hole and a minimum panel thickness of 0.056 inches with a 5/16-24 threaded fastener interface.

Installation Notes

Installation is performed by sheet metal fabricators, HVAC technicians, or electricians using a press tool or arbor press sized for the 0.411-inch body diameter. De-energize and lock out all electrical equipment before servicing any panel or enclosure. Ensure the mounting hole diameter matches the 0.413-inch specification before pressing to achieve proper clinch engagement. Do not hammer install without a properly aligned press tool, as off-axis force can distort the panel or compromise thread integrity.
