Machined from 303 stainless steel with a plain bright finish, this standoff accepts a 4-40 threaded fastener and provides a fully threaded interior through its 1\/4-inch overall length. The hex body measures 3\/16 inches across flats, allowing for standard hex driver or nut driver installation. It meets QQ-S-763 stainless steel fastener specifications and is suited for applications where corrosion resistance and dimensional accuracy are required.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in residential and commercial electronic control board assemblies, HVAC control panels, terminal boards, and general electronics enclosures where secure board-to-surface spacing is needed. Electricians, electronics technicians, and control board service professionals install these as OEM-style hardware components during board mounting, replacement, or panel fabrication. The compact 1\/4-inch length is typical for tight-clearance PCB stacking applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale 4-40 thread accepts standard 4-40 machine screws for secure board attachment\u003c\/li\u003e\n  \u003cli\u003eFully threaded interior with 1\/4-inch thread depth for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e303 stainless steel construction meets QQ-S-763 specification for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHex body profile at 3\/16 inches across flats allows positive torque with standard tooling\u003c\/li\u003e\n  \u003cli\u003ePlain bright finish with no coating to interfere with electrical grounding contact\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/4-inch overall length suited for tight PCB spacing and shallow standoff applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 female hex standoff for use in PCB mounting, electronic enclosures, and control panel assemblies requiring a 1\/4-inch overall length hex standoff with stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electricians or electronics technicians during control board mounting or panel assembly work. De-energize all circuits and discharge any capacitors before handling PCBs or control boards. Use a correctly sized hex driver or nut driver matching the 3\/16-inch across-flats dimension to avoid rounding the hex body. Do not over-torque the standoff into tapped holes, as stainless steel fasteners in aluminum panels are susceptible to galling.\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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 0.25 inches (fully threaded)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\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: Plain (Bright\/Uncoated)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\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: 1\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: P293M09F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51755546673458,"sku":"P293M09F16440","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c204231ba700634133d0035d8f47894.jpg?v=1788955938","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p293m09f16440-hex-standoff-4-40-1-4in","provider":"Voomi Supply","version":"1.0","type":"link"}
