Manufactured from Grade 2 steel with a zinc-plated finish per ASTM B633 and QQ-S-633 Type 1, this spacer delivers corrosion resistance suitable for indoor electronic assemblies. It measures 1 inch overall length, with a 0.089-inch inside diameter and a 3\/16-inch (0.1875-inch) outside diameter. Sized for a number 2 screw, it is installed by electronics assembly technicians, HVAC control board service techs, and electricians working on panel or PCB-level hardware.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used in residential and light commercial applications wherever a number 2 screw is required to mount or stack circuit boards at a precise 1-inch standoff. Typical install scenarios include control board mounting in HVAC equipment, electrical enclosures, and low-voltage electronic assemblies. The round body and unthreaded female design allow a fastener to pass through or seat without thread engagement in the spacer body itself, relying on the mating hardware for retention.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 2 steel construction with zinc-plated finish per ASTM B633 and QQ-S-633 Type 1\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded round body accepts a number 2 screw\u003c\/li\u003e\n  \u003cli\u003e1 inch overall length with tight length tolerance of -0.005 to 0.005 inches\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\u003e3\/16-inch (0.1875-inch) outside diameter for compact PCB spacing applications\u003c\/li\u003e\n  \u003cli\u003eConforms to ASTM B633 and QQ-S-633 Type 1 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit spacer for circuit board assemblies requiring a number 2 screw, 1-inch standoff, female unthreaded round spacer in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics assembly technicians or qualified service personnel working on control boards and PCB assemblies. Always de-energize and discharge any capacitors in the assembly before handling circuit boards or fasteners. Use appropriately sized number 2 hardware and ensure the mating screw length accounts for the full 1-inch spacer height plus board and mounting surface thickness. Avoid over-tightening, which can stress the board substrate or distort the spacer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel, Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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: Number 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\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 (3\/16 inches)\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: S341M10F21C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739022393650,"sku":"S341M10F21C","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_05a73fcc-2088-48bf-83fd-16ee19615690.jpg?v=1788808131","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s341m10f21c-circuit-board-spacer-1in","provider":"Voomi Supply","version":"1.0","type":"link"}
