Manufactured from Grade 303 stainless steel to QQ-S-763 specification, it delivers corrosion resistance and dimensional stability in demanding environments. The spacer measures 4 mm overall length with a 6 mm outside diameter and accepts an M4 screw through an inside diameter ranging from 4.2 to 4.8 mm. The bright uncoated finish is left bare to preserve tight tolerances. Electrical and electronics technicians, control board assemblers, and field service techs working on commercial HVAC or industrial controls routinely use spacers of this type when mounting or replacing circuit boards.\u003c\/p\u003e\u003cp\u003eThis spacer suits applications where a PCB must be held a fixed distance from a chassis, enclosure panel, or secondary board. It is appropriate for use in control panel assemblies, HVAC system control boards, variable-frequency drive housings, and similar electronic assemblies that require metric M4 hardware. The round body and unthreaded female bore allow the fastener to pass through cleanly, making installation straightforward in both new builds and field replacement scenarios. The metric M4 sizing aligns with standard IPC and commercial electronics assembly practices.\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 bore accepts M4 screws with inside diameter range of 4.2 to 4.8 mm\u003c\/li\u003e\n\u003cli\u003e4 mm overall length with tight length tolerance of plus or minus 0.130 mm for consistent standoff height\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter round body for stable seating on PCB mounting pads\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains dimensional accuracy without added coating thickness\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 10 units supports both service stock and bulk assembly needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric M4 round circuit board spacer suitable for PCB mounting applications requiring a 4 mm standoff height and 6 mm OD footprint in assemblies using M4 fastener hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or field service personnel working on control board assemblies. Always de-energize and lock out the equipment before handling any circuit board or internal electronic components. Use appropriately sized M4 fasteners and a calibrated torque driver to avoid cracking the PCB substrate. Follow applicable IPC assembly standards and the equipment manufacturer's service documentation when replacing or installing circuit board hardware.\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\u003eThread Size\u003c\/strong\u003e: M4\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: 4 mm\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\u003eInside Diameter\u003c\/strong\u003e: 4.2 to 4.8 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\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: 0.00296 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: MS1007M07F16F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51738771390770,"sku":"MS1007M07F16F","price":21.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/269ba5eaab313092ea252813038b6163_950c4a1e-5e5e-4d18-89bd-9f694476ce28.jpg?v=1788804223","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1007m07f16f-circuit-board-spacer-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
