It is designed to create a precise standoff gap between a printed circuit board and a mounting surface or adjacent board layer. The spacer accepts a number 6 screw, has an overall length of 0.25 inches, an inside diameter of 0.141 inches, and an outside diameter of 0.3125 inches. The uncoated aluminum finish keeps weight low while providing adequate rigidity for typical PCB mounting applications. Licensed electricians and electronics technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used wherever a consistent, low-profile standoff is required on a circuit board assembly. Common applications include control boards in HVAC equipment, electrical panels, and commercial electronics enclosures where a number 6 fastener pattern is specified. The female unthreaded bore accepts a mating screw passed through the board stack, allowing secure, repeatable positioning. The inch-system dimensions and QQ-A-225A material certification make it a direct fit for mil-spec and commercial-grade PCB assemblies requiring aluminum standoffs at the 5\/16-inch OD form factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded bore sized for a number 6 screw with inside diameter of 0.141 inches\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.25 inches with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.3125 inches with round body profile for consistent seating\u003c\/li\u003e\n  \u003cli\u003eAluminum grade T-3 construction per QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no added coating thickness to affect fitment or clearance\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches for controlled screw engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install aluminum board spacer for circuit board assemblies requiring a number 6 screw, 0.25-inch overall length, and 0.3125-inch outside diameter in inch-system configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed electrician or qualified electronics technician. De-energize and lock out all power to the board assembly before servicing. Verify screw length and thread engagement depth against the assembled stack before torquing fasteners to avoid cracking the PCB substrate. Handle aluminum spacers carefully to avoid burrs that could damage board traces or affect seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum Grade T-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-A-225A Comp 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: Number 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\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: S793-MO4-F16-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740546761010,"sku":"S793-MO4-F16-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_f55f976d-100c-48a5-960c-e8d56908fcd6.jpg?v=1788825858","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s793-mo4-f16-g-round-board-spacer-6-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
