Machined from Grade 2 steel with a zinc-plated finish meeting ASTM B633 and QQ-S-633 Type 1 standards, this spacer provides corrosion resistance and dimensional consistency in electronic assemblies. It measures 1 inch in overall length, 0.141 inches inside diameter, and 0.375 inches outside diameter, sized for Number 6 screw hardware. Licensed electricians, electronics technicians, and HVAC control board installers use this type of hardware when mounting PCBs in control panels, junction boxes, and equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for residential and light commercial applications wherever a Number 6 fastener is used to mount a circuit board. Common install scenarios include HVAC control board assemblies, electrical panel sub-mounts, and industrial enclosure PCB installations. The female unthreaded body accepts a Number 6 screw passed through a mating hole in the board, creating a stable, isolated standoff. Its round body profile and standardized dimensions make it a direct fit in applications requiring tight length and diameter tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded round body accepts Number 6 screws for straightforward board mounting\u003c\/li\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\u003e1 inch overall length with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e0.141 inch inside diameter with an inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e0.375 inch outside diameter provides stable seating on standard PCB mounting holes\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; consistent with standard North American fastener specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style standoff spacer for circuit board assemblies using Number 6 screw hardware in inch-measurement fastener systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electricians, electronics technicians, or qualified HVAC service professionals. De-energize all circuits and discharge any capacitors in the control board assembly before handling PCBs or fastener hardware. Use a correctly sized Number 6 screw and verify board hole alignment before seating the spacer to avoid cracking solder joints or stressing board traces. Follow applicable NEC guidelines when working inside electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 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\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: Number 6\u003c\/li\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\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 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: S1111-M10-F21-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743295897906,"sku":"S1111-M10-F21-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7532f7b0d02fa8993f705a02b40c701f.jpg?v=1788845237","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1111-m10-f21-g-round-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
