Machined from aluminum grade T-3 to the QQ-A-225A Comp 2 fastener standard, it accepts a number 4 screw and measures 0.875 inches in overall length with a 0.3125-inch outside diameter and a 0.116-inch inside diameter. The uncoated finish keeps the profile clean and dimensionally consistent. Electricians, electronics technicians, and panel builders use spacers like this when assembling control boards, relay panels, and circuit board mounting frames where repeatable standoff height and secure fastening are required.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for residential and commercial electronic control assemblies, HVAC control boards, relay panels, and general PCB mounting applications where a number 4 fastener is used. Its compact outside diameter of 0.3125 inches and tight length tolerance of plus or minus 0.005 inches make it a reliable choice for precision-sensitive board layouts. The female unthreaded body accepts a number 4 screw passed through from the board side, drawing the board firmly against the spacer shoulder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded round body accepts number 4 screw for secure PCB standoff mounting\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.875 inches with length tolerance of -0.005 to 0.005 inches for repeatable standoff height\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 0.3125 inches and inside diameter of 0.116 inches with inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003eAluminum grade T-3 construction per QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n\u003cli\u003eUncoated finish maintains dimensional accuracy without added coating thickness\u003c\/li\u003e\n\u003cli\u003eInch measurement system; sold individually\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 board mounting applications requiring a number 4 screw, round body, female unthreaded aluminum standoff.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or electricians during control board assembly or replacement. De-energize all circuits before handling circuit boards or installing standoff hardware. Use a number 4 screw of appropriate length for the board stack-up; do not overtighten, as aluminum spacers can deform under excessive clamp load. Follow applicable electrical codes and board manufacturer mounting guidelines when positioning spacers.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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: 0.875 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: S833-MO4-F16-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743362941234,"sku":"S833-MO4-F16-E","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_10a20a35-f9ce-4516-a81e-8a688b1351a1.jpg?v=1788846181","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s833-mo4-f16-e-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
