Machined from Grade 303 stainless steel to the QQ-S-763 fastener standard, this spacer offers corrosion resistance and dimensional stability in demanding environments. It has an overall length of 23 mm (approximately 0.906 inches), an outside diameter of 6 mm (approximately 0.236 inches), and an inside diameter range of 4.2 to 4.8 mm (approximately 0.165 to 0.189 inches) to accept M4 screws. The uncoated bright finish keeps the surface clean and free of coating buildup that could affect fit tolerance.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in HVAC control boards, electrical enclosure assemblies, variable-frequency drives, and similar trade-grade electronic equipment where reliable PCB mounting hardware is required. Installers and panel builders working on commercial or residential electronic controls will find this spacer appropriate for any application requiring a metric M4 standoff with a 23 mm stack height and a round stainless body.\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\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded design accepts M4 screws with inside diameter range of 4.2 to 4.8 mm\u003c\/li\u003e\n\u003cli\u003eOverall length of 23 mm with a tight length tolerance of -0.13 to 0.13 mm for precise standoff control\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter with round body profile for consistent seating against PCB surfaces\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains dimensional integrity without coating-related dimensional variation\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 10 units supports component-level procurement for service and assembly work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric M4 PCB standoff spacer for use in circuit board assemblies requiring a female unthreaded round spacer with a 23 mm overall length and 6 mm outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified electronics technicians or licensed electricians familiar with PCB mounting hardware. De-energize all equipment and discharge any stored energy before working inside control enclosures or panels. Use properly sized M4 fasteners and avoid over-tightening, which can distort the board or damage the spacer seating surface. Follow applicable NEC guidelines and equipment manufacturer specifications when servicing or assembling control panels.\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\u003eScrew Size\u003c\/strong\u003e: M4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 23 mm (approximately 0.906 inches)\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\u003eOutside Diameter\u003c\/strong\u003e: 6 mm (approximately 0.236 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\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\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: 0.0108 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: MS1045M07F16F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51728498295090,"sku":"MS1045M07F16F","price":76.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/269ba5eaab313092ea252813038b6163_0273c66b-066d-4f1f-86e4-48161fa1259e.jpg?v=1788692195","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1045m07f16f-circuit-board-spacer-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
