Built from 18-8 \/ 303 stainless steel per the QQ-S-763 fastener standard, it delivers corrosion resistance and mechanical stability in tight electrical enclosures. The spacer measures 0.5 inches overall length with a 0.3125-inch outside diameter and a 0.116-inch inside diameter sized for a 4 screw. It ships uncoated, ready for immediate installation. Electricians and electronics technicians use this spacer when securing control boards, relay panels, and similar PCB assemblies inside HVAC, electrical, and automation enclosures.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for residential and light commercial control board mounting applications where a 4 fastener and a 0.5-inch standoff height are specified. It is commonly installed in HVAC control panels, motor drives, and electrical enclosures that require a corrosion-resistant, dimensionally precise standoff. The female unthreaded body accepts a screw through the board from above, bearing down on the spacer to secure the board at the correct height above the chassis or sub-panel surface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18-8 \/ 303 stainless steel construction per QQ-S-763 for corrosion resistance in demanding enclosure environments\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded body sized for a 4 screw, 0.116-inch inside diameter\u003c\/li\u003e\n\u003cli\u003e0.5-inch overall length with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e5\/16-inch (0.3125-inch) outside diameter in a compact round body profile\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  no outgassing or coating contamination risk near sensitive PCB components\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches for consistent fastener fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation spacer for circuit boards requiring a 4 screw, female unthreaded, round standoff with a 0.5-inch overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed electricians or qualified electronics technicians. Always de-energize and lock out the enclosure before handling any control board or PCB assembly. Use the correct 4 fastener to avoid stripping the mating threads or deforming the spacer bore. Verify the installed spacer height provides adequate clearance between the PCB and chassis to prevent electrical shorts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel 18-8 \/ 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\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\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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-M07-F16-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51741173547314,"sku":"S809-M07-F16-E","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_36683f49-76be-49b2-bc07-d6fc0cf0a0ce.jpg?v=1788829820","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s809-m07-f16-e-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
