It measures 0.5 inches overall length (OAL) with a 0.3125-inch outside diameter and a 0.116-inch inside diameter, sized for a 4 screw application. The uncoated finish leaves the aluminum bare, which suits most standard PCB standoff applications where anodizing or plating is not required. Installers working on control board assemblies, panel builds, or electronic enclosure work use this spacer to maintain consistent board-to-chassis clearance and prevent contact shorts.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in residential and commercial control board assemblies, electrical enclosures, and electronic panel builds where a 4 screw size and female unthreaded configuration are specified. It is appropriate for any application requiring a compact aluminum standoff within the inch measurement system. Electricians, HVAC controls technicians, and electronics assembly professionals typically specify this style of spacer during board mounting or panel fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded round body accepts a 4 screw for secure board mounting\u003c\/li\u003e\n\u003cli\u003e0.5-inch OAL with tight length tolerance of -0.005 to 0.005 inches for consistent stack height\u003c\/li\u003e\n\u003cli\u003e0.116-inch inside diameter with tolerance of 0.000 to 0.010 inches for reliable fastener fit\u003c\/li\u003e\n\u003cli\u003e0.3125-inch outside diameter provides stable board support footprint\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 additional plating or anodizing to affect dimensional tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style aluminum circuit board spacer for use with 4 screw fasteners in inch-system PCB mounting and electronic enclosure applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians or electronics technicians during control board assembly or panel fabrication. De-energize all circuits and discharge any stored energy in the assembly before handling circuit boards or installing standoffs. Use the appropriate 4 screw driver or nut driver and avoid overtightening, which can crack PCB mounting holes or distort the spacer body. Verify stack height requirements against board clearance specifications before finalizing fastener length selection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 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: 4\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: 0.5 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\u003eOutside Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.116 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\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: S809-MO4-F16-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51742288904498,"sku":"S809-MO4-F16-E","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_036bef3f-d2f3-49aa-a5f9-2c069a2a9d01.jpg?v=1788836508","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s809-mo4-f16-e-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
