Constructed from brass with a zinc-plated finish meeting ASTM B633 and QQ-B-626 Comp 22 Type 1 standards, this spacer provides reliable standoff height and electrical isolation between circuit boards and chassis surfaces. It measures 14 mm overall length with a 6 mm outside diameter and an inside diameter ranging from 3.2 mm to 3.6 mm. The zinc finish adds corrosion resistance suitable for light-duty electronic enclosure environments. Electronics assembly technicians and field service techs working on control boards in HVAC, electrical, and industrial equipment will find this a direct metric-standard replacement spacer.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in residential and commercial electronic control board assemblies, including HVAC control panels, industrial enclosures, and general PCB mounting applications where an M3-thread standoff is required. The metric sizing makes it appropriate for equipment designed to metric fastener standards. It installs between the circuit board and a mounting surface to maintain consistent board clearance and prevent unwanted contact.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded body accepts M3 screw hardware for secure PCB standoff mounting\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc-plated finish per ASTM B633 and QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n\u003cli\u003e14 mm overall length with tight length tolerance of -0.13 mm to 0.13 mm for consistent stack height\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter with 3.2 mm to 3.6 mm inside diameter range\u003c\/li\u003e\n\u003cli\u003eRound body shape for straightforward installation in standard PCB mounting hole patterns\u003c\/li\u003e\n\u003cli\u003eMetric system sizing compatible with M3 fastener assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric M3 round female unthreaded circuit board spacer suitable for PCB standoff applications requiring a 14 mm overall length and 6 mm outside diameter in brass construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics technicians or control board service professionals. De-energize and fully power down the equipment before servicing any circuit board assembly. Use appropriately sized M3 screws and a calibrated torque driver appropriate to the board manufacturer's guidelines. Ensure the spacer seating surface is clean and flat to maintain proper board clearance and prevent stress on PCB mounting holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eFastener Standard\u003c\/strong\u003e: ASTM B633, QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3\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: 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.2 mm to 3.6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 mm to 0.270 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.130 mm to 0.130 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0173 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MS1027M01F21D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51750787973426,"sku":"MS1027M01F21D","price":24.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebd8695a24e2b6532e3d3f30a7e1347f_5aae1df6-36df-4bae-aec4-1a2a9b054be7.jpg?v=1788919704","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1027m01f21d-round-board-spacer-m3-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
