Machined from Grade 303 stainless steel to the QQ-S-763 fastener standard, this spacer provides corrosion resistance and dimensional consistency in demanding environments. It accepts a No. 2 screw, measures 0.25 inches in overall length, and has an inside diameter of 0.089 inches with an outside diameter of 0.1875 inches. The bright uncoated finish leaves the base material exposed, making it suitable for applications where coating adhesion or conductivity concerns apply. Electronics assemblers and field technicians use this spacer in PCB mounting applications across HVAC control boards, electrical enclosures, and industrial equipment.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in residential and commercial electronics assemblies where a No. 2 fastener is specified and precise board standoff is required. Typical applications include mounting control boards inside HVAC air handlers, furnace control modules, and electrical panel assemblies. Its small form factor and stainless steel construction make it a common choice in environments subject to moisture or temperature cycling. It is sold individually with a minimum order quantity of one unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 303 stainless steel construction meets QQ-S-763 fastener standard for dimensional and material consistency\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded body accepts No. 2 screws for straightforward PCB standoff mounting\u003c\/li\u003e\n\u003cli\u003e0.25 inch overall length with tight length tolerance of -0.005 to 0.005 inches for precise stack height control\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.089 inches with tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 0.1875 inches in a round body profile\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish preserves base material properties without added coating variables\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for circuit board standoff applications using No. 2 screw fasteners in inch-measurement assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electronics assembler or field technician familiar with PCB mounting practices. De-energize all equipment and discharge any capacitors before handling control boards or installing spacers. Use a calibrated torque driver appropriate for No. 2 fasteners to avoid over-tightening, which can crack the PCB or deform the spacer bore. Follow the equipment manufacturer's assembly documentation and any applicable NEC or equipment-specific wiring enclosure requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel Grade 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\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\u003eScrew Size\u003c\/strong\u003e: No. 2\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: 0.089 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: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/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: S293M07F16C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51755616469298,"sku":"S293M07F16C","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_2084ba96-d427-4319-b90e-089c73afe696.jpg?v=1788956975","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s293m07f16c-round-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
