Built from brass and finished with zinc plating per ASTM B633, QQ-B-626 Comp 22 Type 1, this spacer provides corrosion resistance and dimensional stability in electronic assemblies. It accepts a No. 10 screw, measures 0.125 inches overall length, and carries an outside diameter of 0.375 inches with an inside diameter of 0.194 inches. Electronic assembly technicians and industrial maintenance professionals use it wherever controlled board standoff height and secure mechanical support are required.\u003c\/p\u003e\n\u003cp\u003eThis spacer fits standard PCB mounting applications in residential and commercial electronics, control panels, and industrial equipment enclosures. The female unthreaded body allows a No. 10 fastener to pass through while the spacer maintains the specified gap between the circuit board and chassis. Its compact 0.125-inch length suits low-profile assemblies where minimal standoff height is critical. The brass construction supports soldering and conductive grounding paths when required by the assembly design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded round body accepts No. 10 screws for straightforward PCB mounting\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc-plated finish meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards\u003c\/li\u003e\n  \u003cli\u003e0.125-inch overall length with tight length tolerance of -0.005 to 0.005 inches for consistent standoff height\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.194 inches with tolerance of 0.000 to 0.010 inches for reliable fastener fit\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.375 inches provides stable bearing surface against the PCB or chassis\u003c\/li\u003e\n  \u003cli\u003eInch-system dimensions suit standard North American PCB hardware and panel layouts\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 requiring a No. 10 screw, female unthreaded, round brass standoff with a 0.125-inch overall length and 0.375-inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics assembly technicians or qualified maintenance personnel. De-energize and fully discharge the circuit board assembly before handling any PCB hardware. Use the appropriate No. 10 fastener and a calibrated torque driver to avoid deforming the unthreaded brass body. Follow applicable assembly drawings and IPC standards for PCB standoff installation procedures.\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: 0.125 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\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\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: S1055-M01-F21-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743235080498,"sku":"S1055-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_ed6df802-66e8-4ff0-8597-85e5be15d691.jpg?v=1788844306","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1055-m01-f21-i-circuit-board-spacer-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
