Built 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 electronics assemblies in HVAC control boards, electrical enclosures, and industrial panel applications. It measures 0.875 inches overall length with a 0.5 inch outside diameter and a 0.194 inch inside diameter, sized for number 10 screw installations. Electronic technicians, panel builders, and field service technicians working on control boards use this spacer to provide consistent board-to-chassis separation and electrical isolation.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for residential and commercial HVAC control board assemblies, electrical enclosures, and general-purpose PCB mounting applications requiring a number 10 screw size. Its steel construction and zinc-plated surface make it appropriate for indoor environments where light corrosion resistance is needed. Panel builders and controls technicians typically install these during board replacement or new panel assembly work where consistent standoff height is critical to safe and reliable circuit board operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded body accepts number 10 screws for straightforward PCB mounting\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM B633 and QQ-S-633 Type 1 standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for electronics enclosure use\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.875 inches with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches ensures consistent screw fit\u003c\/li\u003e\n  \u003cli\u003eRound body shape with 0.5 inch outside diameter for standard PCB footprint compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spacer for circuit board assemblies using number 10 screw fasteners in HVAC controls, electrical panels, and general electronics enclosures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians, panel builders, or HVAC controls technicians. Always de-energize the control panel or circuit board assembly and follow applicable NFPA 70 (NEC) lockout\/tagout procedures before handling PCBs or spacers. Use appropriate non-marring tools when seating spacers to avoid deforming the zinc plating or distorting the board mounting holes. Do not over-torque fasteners through the unthreaded bore, as this spacer is female unthreaded and relies on the mating screw for clamping force.\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: 10\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.194 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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standards\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\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: S1383-M10-F21-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740294775090,"sku":"S1383-M10-F21-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_2792de0c-4c5c-4e52-89a6-f4b088154e13.jpg?v=1788824072","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1383-m10-f21-i-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
