Machined from aluminum grade T-3 to the QQ-A-225A Comp 2 fastener standard, this spacer measures 5\/16 inches overall length (0.3125 inches) with a 0.194-inch inside diameter and a 5\/16-inch outside diameter. It is sized for a 10 screw and ships uncoated. Electronics assemblers, panel builders, and field technicians use this type of spacer when mounting control boards inside HVAC equipment, electrical enclosures, and similar assemblies where reliable board support is required.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for light commercial and residential applications wherever a 10 screw mounting pattern is used to secure a circuit board. Typical use cases include HVAC control board installations, industrial panel assemblies, and any enclosure where aluminum construction is preferred for its weight and corrosion resistance. The female unthreaded design accepts a mating fastener from below, creating a fixed standoff between the board and the chassis surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum grade T-3 construction per QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts 10 screw hardware\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch overall length (0.3125 inches) with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e0.194-inch inside diameter with inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eRound body profile, 5\/16-inch outside diameter\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no additional plating or coating to affect dimensional tolerances\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 mounting applications requiring a 10 screw, female unthreaded aluminum standoff with a 5\/16-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics assemblers, HVAC technicians, or electricians during control board mounting. De-energize all circuits and discharge any capacitors in the assembly before handling PCBs or installing standoffs. Use fastener hardware matched to the 10 screw size to avoid damage to the unthreaded bore. Follow applicable NEC or equipment-manufacturer guidelines for PCB mounting clearances within electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eScrew Size\u003c\/strong\u003e: 10\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: 0.3125 inches (5\/16 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: 0.194 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 (5\/16 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\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: S797-MO4-F16-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740528574770,"sku":"S797-MO4-F16-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_cb4804fe-3699-4d04-8494-5155b594b917.jpg?v=1788825707","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s797-mo4-f16-i-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
