It measures 1 inch overall length (OAL) with an inside diameter of 0.171 inches and an outside diameter of 0.25 inches. Designed to accept a Number 8 screw, this spacer maintains consistent standoff height between a circuit board and its mounting surface. It carries a bright, uncoated finish and conforms to fastener standard QQ-A-225A Comp 2. Electronics assemblers, control board technicians, and field service pros use this part when precise board-to-chassis clearance is required in HVAC control panels, electrical enclosures, and similar assemblies.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in residential and light commercial control board assemblies where a Number 8 thread size and a 0.25-inch OD profile are specified. Typical applications include PCB mounting in furnace control panels, air handler electrical boxes, and other enclosures that require a low-profile aluminum standoff. Its uncoated aluminum construction makes it appropriate for dry, indoor environments where corrosion exposure is minimal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded body accepts Number 8 screws for secure PCB standoff mounting\u003c\/li\u003e\n\u003cli\u003e1 inch OAL with tight length tolerance of -0.005 to 0.005 inches for consistent stack height\u003c\/li\u003e\n\u003cli\u003e0.171 inch inside diameter with inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003e0.25 inch outside diameter in a round body profile\u003c\/li\u003e\n\u003cli\u003eT3-grade aluminum construction  -  lightweight, non-magnetic, and dimensionally stable\u003c\/li\u003e\n\u003cli\u003eConforms to QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for use in clean, dry enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension Number 8 round female unthreaded circuit board spacer for use in PCB mounting applications requiring a 0.25-inch OD and 1-inch OAL aluminum standoff.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics technicians or qualified service personnel during control board assembly or replacement. Power down and de-energize all equipment before accessing any control board or electrical enclosure. Verify that the mating screw size is Number 8 and that the mounting hole pattern in the board and chassis matches the spacer OD and ID before installation. Do not overtighten fasteners, as unthreaded aluminum spacers can deform under excessive clamping force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.171 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.25 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\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: Number 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: S561-M04-F16-H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743897420082,"sku":"S561-M04-F16-H","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bf1121a6225f8c96b52dbf9a29c576c.jpg?v=1788851059","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s561-m04-f16-h-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
