It accepts an M3 screw, measures 12 mm (0.472 inches) overall length, and carries an outside diameter of 6 mm (0.236 inches) with an inside diameter ranging from 3.2 to 3.6 mm (0.126 to 0.142 inches). Manufactured from Grade 303 stainless steel to the QQ-S-763 fastener standard, this spacer ships uncoated with a bright finish. Electronics assemblers, PCB technicians, and panel-wiring professionals working on control boards in HVAC equipment, electrical enclosures, and industrial panels are the primary installers.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for metric M3 fastener applications where corrosion resistance and dimensional stability are required. Typical use cases include mounting control boards inside HVAC air handlers, furnace control enclosures, and electrical panel assemblies where maintaining consistent board-to-surface spacing prevents shorts and vibration contact. The round body profile and unthreaded female bore accommodate a wide range of M3 fastener styles. The stainless steel construction makes it appropriate for environments with moderate humidity exposure, such as mechanical rooms and rooftop equipment enclosures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 303 stainless steel construction meets QQ-S-763 fastener standard for corrosion resistance and dimensional consistency\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded bore accepts M3 screws with inside diameter tolerance of 0.000 to 0.270 mm for a reliable slip fit\u003c\/li\u003e\n\u003cli\u003e12 mm overall length with a tight length tolerance of -0.130 to 0.130 mm ensures precise standoff spacing\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter round body provides stable, low-profile board support\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating thickness variation to affect fit or electrical grounding contact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for M3 screw metric fastener systems as an OEM-style circuit board spacer for PCB standoff applications in control boards, electrical enclosures, and panel assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics assemblers or licensed electricians during control board mounting or panel assembly. De-energize all circuits and discharge any capacitors before working inside electrical enclosures or HVAC control compartments. Use calibrated metric hand tools to avoid over-torquing the M3 fastener through the unthreaded bore, which can distort the spacer or crack the PCB. Follow applicable NEC guidelines when installing or replacing control boards in electrical enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel Grade 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Thread 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: 12 mm (0.472 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\u003eOutside Diameter\u003c\/strong\u003e: 6 mm (0.236 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.2 to 3.6 mm (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\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: 0.00632 pounds\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: MS1023M07F16D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51727990620466,"sku":"MS1023M07F16D","price":30.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/269ba5eaab313092ea252813038b6163_c09bb273-ff80-4639-b6ac-4ef1d457cc82.jpg?v=1788685617","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1023m07f16d-circuit-board-spacer-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
