It is designed to create a fixed standoff distance between a printed circuit board and a mounting surface or secondary board. The spacer measures 0.1875 inches overall length, with a 0.25-inch outside diameter and a 0.171-inch inside diameter sized to accept a number 8 screw. The uncoated stainless steel construction resists corrosion and handles repeated assembly cycles without galling. Electronics technicians, electrical panel assemblers, and field service techs working on control boards install this type of spacer during board mounting and replacement tasks.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in residential and light commercial control board assemblies, HVAC equipment PCB mounting, electrical enclosures, and other precision electronic assemblies where consistent board standoff height and corrosion resistance are required. Its compact 3\/16-inch length makes it appropriate for applications with tight clearance between a control board and the chassis or mounting bracket beneath it. It is sold and packaged individually, making it practical for single-unit repairs and service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 303 stainless steel construction meets QQ-S-763 fastener standard for corrosion resistance and dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded bore accepts a number 8 screw for straightforward board mounting\u003c\/li\u003e\n  \u003cli\u003e0.1875-inch overall length with a tight length tolerance of -0.005 to 0.005 inches for precise standoff height\u003c\/li\u003e\n  \u003cli\u003e0.25-inch outside diameter and 0.171-inch inside diameter with inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eUncoated finish eliminates coating thickness variability and is compatible with stainless hardware throughout the assembly\u003c\/li\u003e\n  \u003cli\u003eRound body shape seats cleanly against PCB mounting holes and flat chassis surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spacer for circuit board assemblies requiring a number 8 screw, female unthreaded round standoff with a 3\/16-inch overall length in stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or qualified electrical service professionals. Power down and de-energize all equipment before removing or installing control boards or associated hardware. Use the appropriate screwdriver or nut driver sized for the number 8 fastener and avoid overtightening, which can crack PCB mounting pads. Follow applicable NEC guidelines and equipment manufacturer service documentation when accessing electrical enclosures or control boards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.1875 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\u003c\/strong\u003e: 0.171 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\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\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: 18-8 303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\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: S509-M07-F16-H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51742325670194,"sku":"S509-M07-F16-H","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_dae89219-85b7-4ed0-a512-9f06698b71a1.jpg?v=1788836770","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s509-m07-f16-h-circuit-board-spacer-8","provider":"Voomi Supply","version":"1.0","type":"link"}
