Machined from Grade 2 steel with a zinc-plated finish per ASTM B633 and QQ-S-633 Type 1, it provides corrosion resistance in typical indoor electronic assembly environments. The spacer measures 3\/16 inches overall length (0.1875 inches), 3\/8 inches outside diameter (0.375 inches), and 0.141 inches inside diameter, and is sized for No. 6 screws. It is installed by electronics assembly technicians, panel builders, and control board service professionals working on circuit board mounting and repair applications.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used in residential and commercial electronic control panel assemblies where consistent PCB standoff height is required. It is suitable for HVAC control boards, electrical enclosure assemblies, and similar applications where a No. 6 screw fastener is the standard mounting hardware. The female unthreaded body accepts a No. 6 screw passed through the board and spacer during installation. Single-piece packaging makes it appropriate for replacement or repair work where only one spacer is needed at a time.\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 body accepts No. 6 screws for straightforward through-bolt installation\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3\/16 inches (0.1875 inches) provides consistent PCB standoff height\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.141 inches with a tolerance of 0.000 to 0.010 inches for reliable screw fitment\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 3\/8 inches (0.375 inches) with round body shape for even load distribution\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.005 to 0.005 inches ensures dimensional consistency across assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or assembly spacer for circuit board mounting applications requiring a No. 6 screw, female unthreaded, round standoff with 3\/16 inch overall length and 3\/8 inch outside diameter in an inch-measurement system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCircuit board spacers are typically installed by electronics assembly technicians or control board service professionals. De-energize and lock out all power to the control panel or circuit board assembly before beginning any spacer replacement or installation work. A No. 6 screw is passed through the PCB mounting hole and through the spacer bore; verify screw length accounts for the full spacer length plus board thickness. Avoid over-torquing fasteners through the unthreaded bore, as this spacer does not provide thread engagement.\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\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. 6\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: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.141 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\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: S1059-M10-F21-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740163965234,"sku":"S1059-M10-F21-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_8cd81dae-7606-47a2-8381-1a3c9119392a.jpg?v=1788823060","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1059-m10-f21-g-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
