Manufactured from 18-8 Grade 303 stainless steel with an uncoated finish, this spacer meets the QQ-S-763 fastener standard. It accepts a Number 6 screw and measures 0.25 inches overall length, 0.141 inches inside diameter, and 0.3125 inches outside diameter. Inside diameter tolerance runs 0.000 to 0.010 inches, and length tolerance is -0.005 to 0.005 inches, making it suitable for applications where dimensional consistency is critical.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used in electronic and electrical assemblies where a circuit board must be mounted at a fixed, repeatable distance from a chassis or sub-panel. Typical applications include control boards in HVAC equipment, industrial enclosures, and other low-voltage electronic assemblies. The stainless steel construction makes it appropriate for environments where mild corrosion resistance is needed. The female unthreaded body accepts a Number 6 machine screw passed through from below, providing a clean, secure mount without threading directly into the board substrate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 Grade 303 stainless steel construction meets QQ-S-763 fastener standard\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts Number 6 screw for straightforward PCB standoff mounting\u003c\/li\u003e\n  \u003cli\u003e0.25 inch overall length provides consistent board clearance\u003c\/li\u003e\n  \u003cli\u003eTight inside diameter tolerance (0.000 to 0.010 inches) ensures reliable screw fit\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy at the mating surfaces\u003c\/li\u003e\n  \u003cli\u003eRound body shape suits standard PCB mounting hole patterns\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 using Number 6 screw hardware in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electricians, electronics technicians, or HVAC controls technicians. De-energize and lock out the equipment before handling any circuit board assembly. Verify that the mating screw length is appropriate for the combined thickness of the board and spacer stack before fastening. Do not overtighten the mating screw, as the unthreaded bore provides no thread engagement and relies on a clamping arrangement from the fastener hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eFastener Standard\u003c\/strong\u003e: QQ-S-763\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\u003eScrew Size\u003c\/strong\u003e: Number 6\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-M07-F16-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743866683698,"sku":"S793-M07-F16-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce00dd8f23a0a23abb86364999b8a116.jpg?v=1788850550","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s793-m07-f16-g-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
