Manufactured from brass to ASTM B633 and QQ-B-626 Comp 22 Type 1 standards, this metric spacer features a zinc-plated finish for corrosion resistance. It measures 15 mm overall length with an outside diameter of 6 mm and an inside diameter ranging from 3.2 to 3.6 mm. The length tolerance is -0.130 to 0.130 mm and the inside diameter tolerance is 0.000 to 0.270 mm, making it suitable for precision PCB standoff applications where consistent board-to-board or board-to-chassis clearance is required.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used in residential and commercial electronic control board assemblies, HVAC control panels, industrial PCB mounting, and general electrical enclosure applications. It provides a rigid standoff between a circuit board and a mounting surface or adjacent board, preventing contact and allowing airflow or wiring clearance beneath the PCB. Electricians, electronics technicians, and HVAC control board service professionals typically install this type of hardware during new panel assembly or board replacement work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards for reliable performance\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion protection in panel and enclosure environments\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded design accepts M3 screws for secure PCB standoff mounting\u003c\/li\u003e\n  \u003cli\u003eTight length tolerance of -0.130 to 0.130 mm supports consistent board clearance\u003c\/li\u003e\n  \u003cli\u003eRound body shape with 6 mm outside diameter fits standard PCB mounting footprints\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 10 units suits service stock and small assembly runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style metric circuit board spacer for M3 screw applications in PCB mounting and standoff configurations across electronic control assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or licensed electricians during PCB assembly or control board service. De-energize and lock out all power to the panel or enclosure before handling circuit boards or mounting hardware. Use appropriately sized M3 fasteners and do not overtighten, as brass spacers can be damaged by excessive torque. Follow applicable NEC guidelines when working inside electrical 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\u003eFor Thread 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: 15 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 to 3.6 mm\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\u003eSystem of Measurement\u003c\/strong\u003e: Metric\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\u003eWeight\u003c\/strong\u003e: 0.018 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: MS1029M01F21D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51733160493362,"sku":"MS1029M01F21D","price":34.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebd8695a24e2b6532e3d3f30a7e1347f_fe881572-a426-4a0d-a906-795cf558d502.jpg?v=1788752094","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1029m01f21d-circuit-board-spacer-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
