Machined from brass and finished with a zinc plating that meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards, this spacer delivers reliable corrosion resistance in demanding environments. It accepts an M3 screw, measures 18 mm overall length, carries an inside diameter range of 3.2 to 3.6 mm, and has a 6 mm outside diameter. Electricians, electronics technicians, and automation integrators use this type of hardware when building or servicing control panels, circuit board assemblies, and enclosures where consistent standoff height and secure fastening are critical.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for metric-standard circuit board mounting applications in both commercial and industrial settings. Typical installations include control panel PCB assemblies, DIN-rail mounted electronics, automation enclosures, and HVAC or electrical equipment control boards requiring precise board-to-board or board-to-chassis standoff distances. The zinc finish makes it appropriate for environments with moderate humidity exposure. Because the unit is sold individually with a minimum order quantity of 10, it is practical for both small repair jobs and higher-volume panel builds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded round body accepts M3 screws for metric-standard PCB mounting\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc plating meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards\u003c\/li\u003e\n  \u003cli\u003e18 mm overall length with a tight length tolerance of -0.13 to 0.13 mm for consistent standoff height\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 3.2 to 3.6 mm with a tolerance range of 0.000 to 0.270 mm\u003c\/li\u003e\n  \u003cli\u003e6 mm outside diameter round body for stable, compact footprint on the board surface\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides moderate corrosion resistance suitable for control panel environments\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 use in electronic assemblies requiring M3 screw-size, female unthreaded standoffs with an 18 mm overall length and 6 mm outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electricians or electronics technicians during control panel assembly or PCB service work. Power down and de-energize all circuits before handling circuit board hardware to prevent electrostatic discharge damage or unintended shorts. Use appropriately sized M3 metric fasteners and avoid overtightening, which can crack or deform the spacer body or the PCB mounting hole. Follow applicable NEC guidelines and equipment manufacturer instructions when installing spacers in listed 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\u003eFastener Standard\u003c\/strong\u003e: ASTM B633, QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew 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: 18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 to 0.13 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\u003eOutside Diameter\u003c\/strong\u003e: 6 mm\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: 0.0096 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: MS1035M01F21D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51749348180274,"sku":"MS1035M01F21D","price":27.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebd8695a24e2b6532e3d3f30a7e1347f_a8af20fd-5441-4bbf-98ac-bfa1f61f9e17.jpg?v=1788904790","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1035m01f21d-round-circuit-board-spacer-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
