It measures 5\/16 inches (0.3125 inches) overall length with a 0.1410-inch inside diameter and a 0.3125-inch outside diameter, sized for number 6 screw applications. The uncoated finish leaves the aluminum bare for maximum electrical conductivity or grounding continuity where coatings would interfere. Licensed electricians, electronics technicians, and industrial maintenance professionals use these spacers to set precise standoff distances between circuit boards and mounting surfaces, protecting PCB traces from contact shorts and mechanical stress.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for light commercial and industrial PCB mounting applications where a compact, low-profile standoff is needed. Typical installations include control boards in HVAC equipment, panel assemblies, power supply enclosures, and similar electronic subassemblies that require a number 6 fastener pattern. The 5\/16-inch body length makes it appropriate for tight chassis layouts where larger standoffs would not fit without modifying adjacent hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded bore accepts number 6 screws with an inside diameter of 0.1410 inches\u003c\/li\u003e\n  \u003cli\u003eCompact 5\/16-inch overall length suits tight PCB mounting cavities\u003c\/li\u003e\n  \u003cli\u003eAluminum grade T-3 construction provides lightweight, corrosion-resistant performance\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-A-225A Comp 2 fastener standard for consistent dimensional quality\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves bare-metal contact for grounding or continuity applications\u003c\/li\u003e\n  \u003cli\u003eRound body shape with 0.3125-inch outside diameter fits standard mounting cutouts\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 6 screw, female unthreaded, round aluminum standoff with a 5\/16-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or qualified electricians. De-energize the circuit board assembly and discharge any capacitors before handling PCB hardware. Use a number 6 fastener sized appropriately for the board thickness and chassis material  -  do not overtighten through an unthreaded bore, as aluminum spacers can deform under excessive clamp load. Follow applicable NEC or equipment-manufacturer guidelines for PCB mounting clearances and grounding continuity.\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: 6\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\u003eInside Diameter\u003c\/strong\u003e: 0.1410 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\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 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-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743485919538,"sku":"S797-MO4-F16-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_737cf998-415b-42bd-b3d2-4720cb5c2ef7.jpg?v=1788847577","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s797-mo4-f16-g-round-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
