Built from Grade 2 steel with a zinc-plated finish per ASTM B633 and QQ-S-633 Type 1, this spacer provides corrosion resistance in typical panel and enclosure environments. It accepts a No. 4 screw and measures 0.625 inches overall length, with an inside diameter of 0.116 inches and an outside diameter of 0.1875 inches. Electronics assembly technicians and field service professionals use it when mounting control boards in HVAC equipment, electrical enclosures, and similar applications.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in residential and light commercial applications wherever a No. 4 fastener is used to mount a circuit board. Common installation scenarios include furnace control board mounting, packaged unit electronics bays, and general electrical enclosure assemblies. The inch-system dimensions and standard No. 4 screw sizing make it a straightforward fit for domestic OEM-style control board installations. Sold individually, it is appropriate for single-unit service calls or small repair jobs requiring exact replacement of an existing standoff spacer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded round body accepts No. 4 screw for clean board standoff mounting\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides reliable mechanical strength for panel and enclosure use\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish meets ASTM B633 and QQ-S-633 Type 1 for corrosion protection\u003c\/li\u003e\n  \u003cli\u003e0.625 inch overall length with tight length tolerance of -0.005 to 0.005 inches for consistent board clearance\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches ensures reliable fastener fit\u003c\/li\u003e\n  \u003cli\u003eInch-system dimensions for straightforward compatibility with domestic hardware and tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service spacer for circuit board mounting applications using No. 4 screw hardware in standard inch-system enclosures and control panels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics assembly technicians or field service professionals working on control boards in de-energized equipment. Always disconnect power and verify zero voltage at the board before removing or replacing standoff spacers. Use a hand driver sized for No. 4 fasteners to avoid overloading the unthreaded female body. Follow applicable equipment manufacturer guidelines for board mounting torque and clearance requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B633, QQ-S-633 Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 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: 0.625 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: 0.116 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\u003eOutside Diameter\u003c\/strong\u003e: 0.1875 inches\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: S317M10F21E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51747432956210,"sku":"S317M10F21E","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_48846aa0-0284-41c1-a3a0-f617436c3021.jpg?v=1788880111","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s317m10f21e-circuit-board-spacer-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
