Manufactured from brass to ASTM B633 and QQ-B-626 Comp 22 Type 1 standards, it carries a zinc-plated finish for corrosion resistance. The spacer measures 9 mm (approximately 0.354 inches) overall length with a 6 mm (approximately 0.236 inches) outside diameter and an inside diameter ranging from 3.2 mm to 3.6 mm (approximately 0.126 to 0.142 inches). It is installed by electronics technicians and electrical assemblers in PCB mounting, standoff, and stacking applications where a non-threaded female spacer is required between a board and a chassis or between stacked boards.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in control board assemblies, industrial electronics enclosures, HVAC control panels, and similar low-voltage circuit board installations. The metric M3 sizing makes it appropriate for both residential and light commercial electronic subassemblies. It fits standard PCB standoff layouts where a round brass spacer with zinc finish is specified. Minimum order quantity is 10 units; package quantity is 1 per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction meeting ASTM B633 and QQ-B-626 Comp 22 Type 1 fastener standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in control panel environments\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded bore accepts M3 screws with inside diameter tolerance of 0.000 to 0.270 mm\u003c\/li\u003e\n  \u003cli\u003eOverall length tolerance of -0.130 to 0.130 mm for precise PCB standoff height control\u003c\/li\u003e\n  \u003cli\u003eRound body shape with 6 mm outside diameter fits standard PCB mounting footprints\u003c\/li\u003e\n  \u003cli\u003eMetric measurement system; UNSPSC code 31161816\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 printed circuit board assemblies requiring a round, female unthreaded brass standoff sized for M3 hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or qualified electrical assemblers. De-energize and discharge all capacitors on the circuit board before handling or installing spacers. Use appropriate metric hand tools sized for M3 fasteners; avoid over-tightening, which can crack PCB substrate material or deform the spacer bore. Follow applicable electrical assembly and safety standards for the equipment being serviced.\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\u003eScrew Size\u003c\/strong\u003e: M3\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\u003eOverall Length\u003c\/strong\u003e: 9 mm (approximately 0.354 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 mm (approximately 0.236 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.2 to 3.6 mm (approximately 0.126 to 0.142 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.270 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.130 to 0.130 mm\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: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00552 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: MS1017M01F21D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51752124416306,"sku":"MS1017M01F21D","price":23.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebd8695a24e2b6532e3d3f30a7e1347f_655513d9-ffc3-498c-89b1-83ba6eaa1e20.jpg?v=1788926036","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1017m01f21d-circuit-board-spacer-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
