It features a 1\/4-20 thread size and a low-profile hex head that sits flush with the panel surface after installation. The body diameter measures 0.343 inches and the mounting hole diameter is 0.344 inches, requiring a closely toleranced hole for a firm press fit. Constructed from 18-8 passivated stainless steel, this captive nut resists corrosion in demanding environments. HVAC technicians, electricians, and panel fabricators use this hardware when a threaded fastening point must remain captured in the panel without backing access.\u003c\/p\u003e\n\u003cp\u003eThis captive nut is suited for installation in sheet metal panels, electrical enclosures, HVAC equipment cabinets, and control boxes where a minimum panel thickness of 0.187 inches is present. The hex head profile resists rotation during bolt engagement, eliminating the need for a secondary tool to hold the nut. It is sold in a package of 10 units, making it practical for service trucks, panel shops, and light assembly work requiring small quantities of precision fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 thread size for standard bolt compatibility\u003c\/li\u003e\n  \u003cli\u003eHex head design prevents rotation during fastening without rear access\u003c\/li\u003e\n  \u003cli\u003eFlush mount profile keeps the panel surface clean and unobstructed\u003c\/li\u003e\n  \u003cli\u003e18-8 passivated stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMinimum panel thickness of 0.187 inches accommodates common sheet metal gauges\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 10 units for small-quantity service and repair needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for sheet metal panels and enclosures requiring a 0.344-inch mounting hole and 1\/4-20 thread engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a correctly sized mounting hole of 0.344 inches in the panel before pressing or driving the captive nut into place. Power down and de-energize any enclosure or panel before servicing fasteners in live electrical or HVAC equipment. Use appropriate press or installation tooling to seat the nut flush without deforming the panel material. Verify thread engagement is clean and free of debris before assembling the mating fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Flush Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.029 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.343 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 0.344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Panel Thickness\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivated\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: 3.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161706\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: EF-0420-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51742600036658,"sku":"EF-0420-5","price":38.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9387f1db928c0c69eff5b3fd96face63.jpg?v=1788838281","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ef-0420-5-captive-nut-1-4-20-hex-head-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
