Machined from aluminum grade T3 and left uncoated for a bright finish, it accepts an M4 screw and provides an overall length of 7 mm (approximately 0.276 inches). The inside diameter ranges from 4.2 to 4.8 mm (approximately 0.165 to 0.189 inches) and the outside diameter is 6 mm (approximately 0.236 inches). Electronics assemblers, panel builders, and control board technicians install this spacer when building or servicing HVAC control panels, motor drive assemblies, and similar enclosures that require precise PCB mounting clearance.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for metric M4 fastener applications in light industrial and commercial electronic assemblies. It is commonly used in control panel fabrication, circuit board mounting frames, and equipment enclosures where aluminum construction keeps weight low and resists corrosion without a coating. The round body shape allows consistent seating against PCB mounting holes, and the unthreaded bore accepts a pass-through M4 screw or bolt without thread engagement in the spacer itself.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded bore accepts M4 screws for straightforward pass-through mounting\u003c\/li\u003e\n\u003cli\u003eAluminum grade T3 construction per fastener standard QQ-A-225A Comp 2\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no added coating thickness to affect fit tolerances\u003c\/li\u003e\n\u003cli\u003eOverall length of 7 mm (approximately 0.276 inches) with a tight length tolerance of -0.130 to 0.130 mm\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of 0.000 to 0.270 mm for consistent M4 screw fit\u003c\/li\u003e\n\u003cli\u003eRound body profile with 6 mm outside diameter for compact panel layouts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style round circuit board spacer for metric M4 screw applications in electronic control assemblies, PCB mounting frames, and industrial panel enclosures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics assemblers, panel technicians, and licensed electricians during control board fabrication or replacement. Power down and de-energize all circuits in the enclosure before handling PCBs or installing spacers. Use appropriately sized M4 fastener hardware and apply only hand-tight torque to avoid deforming the unthreaded aluminum bore. Follow applicable NEC guidelines when mounting control boards inside electrical enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-A-225A Comp 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4\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: 7 mm (approximately 0.276 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.2 to 4.8 mm (approximately 0.165 to 0.189 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\u003eOutside Diameter\u003c\/strong\u003e: 6 mm (approximately 0.236 inches)\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\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.00152 pounds\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: MS1013M04F16F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51750357500210,"sku":"MS1013M04F16F","price":17.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0a405ceb63c0dd5c1dbdb7f5517a2d3_3dd3907f-e860-47a0-9adf-cc32df8b17b7.jpg?v=1788915020","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1013m04f16f-round-board-spacer-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
