Manufactured from grade 303 stainless steel with a passivated finish, this standoff resists corrosion and is suitable for environments where surface contamination must be minimized. It features a 4-40 female thread, an overall length of 0.437 inches, and a hex body width across flats of 0.187 inches. The fastening method is self-clinching with a through hole, allowing secure installation directly into sheet metal panels. This hardware is sold in packages of 25 and is sized for use in precision electronic assemblies across HVAC controls, electrical equipment, and industrial applications.\u003c\/p\u003e\u003cp\u003eThis standoff is used wherever circuit boards require rigid, elevated mounting within a chassis or panel. Common applications include residential and commercial HVAC control board assemblies, electrical enclosures, and industrial electronics. The 4-40 thread size is a standard inch-series fastener size widely used in light-gauge sheet metal assemblies. The passivated stainless steel construction makes it appropriate for applications requiring clean, low-contamination hardware. Installation is straightforward for technicians working in panel fabrication, board assembly, or field replacement of control board mounting hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 female thread for standard inch-series board mounting\u003c\/li\u003e\n\u003cli\u003eHex body profile at 0.187 inches width across flats for wrench or driver engagement\u003c\/li\u003e\n\u003cli\u003e0.437 inches overall length provides consistent board standoff height\u003c\/li\u003e\n\u003cli\u003eGrade 303 stainless steel construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003ePassivated finish minimizes surface contamination in sensitive electronic environments\u003c\/li\u003e\n\u003cli\u003eSelf-clinching through-hole fastening method for secure panel installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 inch-series female hex standoff for use in circuit board mounting applications across electronic enclosures, control panels, and equipment requiring self-clinching hardware in sheet metal assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of self-clinching standoffs typically requires a press or squeezing tool to properly seat the standoff into the parent sheet metal panel — do not attempt installation with a hammer, as this can deform the standoff or panel. Power down all circuits and discharge any stored energy before working inside control panels or enclosures. Verify thread engagement and panel material compatibility before pressing. A licensed electrician or qualified panel fabricator should perform installation in line-voltage enclosures subject to NEC requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastening Method\u003c\/strong\u003e: Self Clinching with Through Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: ESOS-440-14\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51731407077682,"sku":"ESOS-440-14","price":40.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bb31a2b55f29266b65ab45d45b35cac_85953bb4-ad48-44eb-8840-b0547b76068a.jpg?v=1788730651","url":"https:\/\/voomisupply.com\/products\/electro-hardware-esos-440-14-hex-standoff-4-40-ss-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
