It measures 0.25 inches in overall length with a 0.25 inch outside diameter and a 0.141 inch inside diameter. The uncoated finish leaves the aluminum bare, which is appropriate for applications where conductivity or weight are concerns. This spacer is sized for number 6 screws and provides a rigid standoff between a PCB and a mounting surface. Electricians, electronics technicians, and equipment assemblers working on control boards and panel assemblies install this type of hardware during new builds and service replacements.\u003c\/p\u003e\n\u003cp\u003eThis spacer suits residential and commercial electronic control board assemblies across HVAC, pool, electrical, and similar trade equipment. It is used wherever a printed circuit board must be held off a chassis or sub-panel at a fixed 0.25 inch standoff height. The compact outside diameter of 0.25 inches keeps the footprint tight in dense board layouts. Applications include furnace control boards, variable-speed drive panels, pump control modules, and other assemblies that use number 6 mounting hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum grade T-3 construction meets QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts number 6 screws for secure PCB standoff mounting\u003c\/li\u003e\n  \u003cli\u003e0.25 inch overall length provides precise, repeatable board-to-chassis clearance\u003c\/li\u003e\n  \u003cli\u003e0.141 inch inside diameter with a tolerance of 0.000 to 0.010 inches for consistent fit\u003c\/li\u003e\n  \u003cli\u003eLength tolerance held to -0.005 to 0.005 inches for tight assembly stacking\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no added coating weight or risk of flaking in confined board areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard number 6 screw circuit board spacer for use in any PCB assembly requiring a 0.25 inch aluminum female unthreaded standoff.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or trade professionals assembling or servicing control board panels. De-energize all circuits and discharge any capacitors before handling PCBs or installing spacers. Use a correctly sized number 6 fastener and do not overtighten, as aluminum spacers can deform under excessive torque. Follow applicable NEC guidelines when reassembling any electrical control enclosure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eOutside Diameter\u003c\/strong\u003e: 0.25 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\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\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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: S513-M04-F16-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739309146418,"sku":"S513-M04-F16-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25d46f7db77f22cdaf8734c40878ae5b.jpg?v=1788812957","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s513-m04-f16-g-circuit-board-spacer-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
