Machined from brass to ASTM B633, QQ-B-626 Comp 22 Type 1 standards and finished with a zinc plating for corrosion resistance, this spacer accepts a No. 10 screw and measures 0.5 inches overall length with a 0.5-inch outside diameter and a 0.194-inch inside diameter. It is suited for electronics assembly, control board mounting, and similar precision fastening applications in trade equipment.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used wherever a circuit board requires a fixed standoff from a chassis, enclosure panel, or secondary board. Typical applications include HVAC control board installations, electrical panel assemblies, and industrial equipment PCB mounting. The female unthreaded bore accepts a No. 10 screw passed through the board, allowing the spacer to act as a rigid standoff without requiring a tapped thread in the spacer body itself. It is installed by electronics assemblers, controls technicians, and electricians during equipment assembly or board replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction meets ASTM B633, QQ-B-626 Comp 22 Type 1 standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in enclosure environments\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded bore sized for No. 10 screw fasteners\u003c\/li\u003e\n  \u003cli\u003e0.5-inch overall length with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e0.194-inch inside diameter with tolerance of 0.000 to 0.010 inches for consistent fit\u003c\/li\u003e\n  \u003cli\u003eRound body profile for uniform standoff and easy alignment during assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style round circuit board spacer for use with No. 10 screw fasteners in PCB standoff and mounting applications across control boards, enclosures, and electronic assemblies requiring a 0.5-inch standoff height.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics assemblers, controls technicians, or licensed electricians working on PCB mounting or control board replacement. Power down and de-energize all equipment before handling circuit boards or installing spacers. Use appropriately sized No. 10 screws and avoid over-torquing, which can crack solder joints or deform the spacer bore. Follow applicable NEC guidelines when working inside energized enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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\u003eScrew Size\u003c\/strong\u003e: No. 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B633, QQ-B-626 Comp 22 Type 1\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: S1359-M01-F21-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740526215474,"sku":"S1359-M01-F21-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_a5930664-31a0-4107-9bbd-4ba700733140.jpg?v=1788825678","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1359-m01-f21-i-circuit-board-spacer-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
