Sized for M4 screws, it measures 14 mm overall length with an outside diameter of 6 mm and an inside diameter ranging from 4.2 mm to 4.8 mm. Machined from Grade 303 stainless steel with a bright uncoated finish, it meets the QQ-S-763 fastener standard. Electricians, electronics technicians, and panel builders use this spacer to maintain consistent board clearance and prevent electrical contact between PCB layers and enclosure surfaces.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in control panels, electrical enclosures, and electronic assemblies where corrosion resistance and dimensional precision are required. The stainless steel construction makes it appropriate for both indoor and light-duty industrial environments. Its metric M4 sizing fits standard metric fastener layouts common in commercial control boards, HVAC equipment electronics, and industrial automation assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 303 stainless steel construction per QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup to affect fit or conductivity\u003c\/li\u003e\n\u003cli\u003eM4 screw compatibility with 4.2 mm to 4.8 mm inside diameter range\u003c\/li\u003e\n\u003cli\u003e6 mm outside diameter in a compact round body profile\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.13 mm to 0.13 mm for consistent stack height\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded design for pass-through fastener configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric M4 female unthreaded round circuit board spacer for use in PCB mounting applications requiring a 14 mm standoff height and 6 mm outside diameter footprint.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or electricians during panel assembly or PCB mounting. De-energize all circuits and discharge any capacitors before working inside control enclosures. Use calibrated torque tools appropriate for M4 metric fasteners to avoid deforming the unthreaded bore. Verify standoff height against PCB layout requirements before final assembly.\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: 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 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\u003eLength Tolerance\u003c\/strong\u003e: -0.130 mm to 0.130 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\u003eWeight\u003c\/strong\u003e: 0.0072 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: MS1027M07F16F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51729740693810,"sku":"MS1027M07F16F","price":22.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/269ba5eaab313092ea252813038b6163_1cf19b85-89cd-4784-b388-403d4f6b0550.jpg?v=1788708786","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1027m07f16f-circuit-board-spacer-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
