Machined from steel with a zinc-plated finish for corrosion resistance, this standoff features a 4-40 thread and measures 0.437 inches in overall length with a 0.187-inch width across flats. It uses a self-clinching with through-hole fastening method, allowing secure press-in installation into sheet metal or PCB material. Electricians, electronics technicians, and HVAC control board assemblers use these standoffs when mounting or replacing control boards in panels, enclosures, and equipment chassis.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for low-voltage control board assemblies, HVAC equipment circuit boards, electrical panel sub-assemblies, and general electronics enclosure work. The hex body shape allows wrench engagement for controlled installation and removal. With inch-system threading at 4-40, it fits standard North American PCB mounting patterns. Sold in a package of 25, it is practical for service technicians stocking hardware for multiple board replacements or for panel assemblers working on production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 female thread accepts standard 4-40 machine screws for PCB mounting\u003c\/li\u003e\n  \u003cli\u003e0.437-inch overall length provides consistent board-to-surface spacing\u003c\/li\u003e\n  \u003cli\u003eHex body shape at 0.187 inches across flats allows wrench-driven installation\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eSelf-clinching with through-hole fastening method for secure press-in mounting\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 25 units to support multi-board service or assembly work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service hardware for circuit board assemblies using 4-40 inch-system standoffs in residential and commercial HVAC control boards, electrical enclosures, and general electronics panel applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed electricians or electronics technicians. Always de-energize and lock out the equipment before handling control boards or standoffs in any electrical enclosure. Self-clinching standoffs require a press or controlled-force installation into the mounting surface and should not be hammered in, as that can deform the hex body or damage the board. Follow applicable NEC guidelines when working inside electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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: 0.16 pounds\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: ESO-440-14ZI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51728488300850,"sku":"ESO-440-14ZI","price":26.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38aeaf4afbdba8caf5a10ab35e13e82d.jpg?v=1788692014","url":"https:\/\/voomisupply.com\/products\/electro-hardware-eso-440-14zi-hex-standoff-4-40-pack-of-25","provider":"Voomi Supply","version":"1.0","type":"link"}
