The clinch design is pressed into a punched or drilled mounting hole, creating a strong threaded insert that stays fixed in the panel. This eliminates the need for a separate nut and backing tool during final assembly. Made from zinc plated steel, the ES-0518-2 provides corrosion resistance suitable for light industrial and commercial enclosure applications. It carries a 5\/16-18 thread size with a minimum panel thickness requirement of 0.0909 inches, making it appropriate for light-gauge sheet metal work.\u003c\/p\u003e\u003cp\u003eThis clinch captive nut is used in applications where a permanent, captive threaded fastener is needed in sheet metal panels, electrical enclosures, HVAC equipment chassis, and structural brackets. It is typically specified during fabrication or service when adding threaded attachment points to panels that cannot accommodate weld nuts or conventional through-bolts. Electricians, HVAC technicians, and sheet metal fabricators install this hardware in both residential and commercial equipment assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 thread for common bolting applications in light industrial assemblies\u003c\/li\u003e\n\u003cli\u003eRound head profile with 0.5 inch head diameter seats flush against panel surface\u003c\/li\u003e\n\u003cli\u003eMinimum panel thickness of 0.0909 inches suits light-gauge sheet metal\u003c\/li\u003e\n\u003cli\u003eMounting hole diameter of 0.413 inches for precise press-fit installation\u003c\/li\u003e\n\u003cli\u003eZinc plated steel construction provides corrosion resistance and durability\u003c\/li\u003e\n\u003cli\u003eHead height of 0.23 inches keeps profile low after installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style clinch captive nut for light-gauge sheet metal panels requiring a permanent 5\/16-18 threaded insert in applications where panel thickness meets the 0.0909 inch minimum requirement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of clinch captive nuts requires a punch press, arbor press, or appropriate clinching tool to press the nut into the pre-drilled or punched mounting hole. Ensure the panel is powered down and de-energized before installing hardware in electrical or HVAC enclosures. The mounting hole diameter must match the specified 0.413 inch dimension for proper clinch engagement. Do not attempt to install by striking with a hammer, as uneven force can distort the nut body and compromise thread integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Clinch Captive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.412 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 0.413 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Panel Thickness\u003c\/strong\u003e: 0.0909 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc Plated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161706\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELECTRO HARDWARE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ES-0518-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739597668658,"sku":"ES-0518-2","price":24.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2adbb570005f3ed4b8b5c26cb753351d_e1635dd8-b849-4a5e-abff-3653fd4e2a75.jpg?v=1788816755","url":"https:\/\/voomisupply.com\/products\/electro-hardware-es-0518-2-round-head-clinch-captive-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
