Machined from aluminum grade T3 and left uncoated with a bright finish, this spacer provides a rigid standoff between a PCB and a mounting surface or between stacked boards. It measures 13 mm overall length with a 6 mm outside diameter and an inside diameter ranging from 4.2 mm to 4.8 mm, accommodating M4 hardware with controlled clearance. The part meets fastener standard QQ-A-225A Comp 2. Electronics technicians, panel builders, and automation integrators use this spacer in control boards, enclosures, and instrumentation assemblies.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for light commercial and industrial electronic panel assemblies where a metric M4 standoff is required. Common install scenarios include PCB mounting inside HVAC control enclosures, electrical panel subassemblies, and instrumentation housings where a non-threaded female body provides a clean pass-through clearance hole. The compact 6 mm OD keeps the footprint minimal on densely populated boards. Because this part ships as a single piece with a minimum order quantity of 10 units, it is typically sourced for small batch assembly or service replacement work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded body accepts M4 screw hardware with 4.2 mm to 4.8 mm internal clearance\u003c\/li\u003e\n\u003cli\u003e13 mm overall length with a tight length tolerance of -0.13 mm to 0.13 mm for consistent stack height\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter in a round body shape for compact PCB footprint\u003c\/li\u003e\n\u003cli\u003eAluminum grade T3 construction provides lightweight, corrosion-resistant standoff performance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish meets QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n\u003cli\u003eMetric system of measurement throughout for direct compatibility with M4 hardware specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-build component for electronic assemblies requiring a metric M4 round circuit board spacer with a female unthreaded body.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics technicians or panel builders during board assembly or service. De-energize all circuits and discharge any capacitive loads before working inside a control enclosure. Use the appropriate M4 fastener and apply even seating pressure to avoid cracking the PCB substrate. Follow applicable IPC assembly standards and enclosure manufacturer guidelines for standoff placement and torque practices.\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\u003eFor Thread Size\u003c\/strong\u003e: M4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Type\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: 13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 mm to 0.13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.2 mm to 4.8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 mm 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\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: 0.00248 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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\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: MS1025M04F16F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51753718808882,"sku":"MS1025M04F16F","price":23.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/122638f2aff2346533a3351c6adea446.jpg?v=1788939971","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1025m04f16f-circuit-board-spacer-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
