Machined from 303 stainless steel with a bright uncoated finish, it meets the QQ-S-763 fastener standard. The M3x0.5 thread runs on both the male pin end and the female threaded bore, with an overall length of 15.76 mm and a body length of 11.00 mm. The hex body measures 4.50 mm across flats, making it compatible with standard hex drivers. Electronics assembly technicians, control panel builders, and field service electricians use this standoff when building or servicing PCB assemblies in HVAC controls, relay panels, and similar equipment.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for metric-threaded PCB mounting applications in residential and light commercial control enclosures, industrial control panels, and instrumentation assemblies. It provides a rigid, corrosion-resistant spacer between board layers or between a board and a chassis surface. The male thread engages a mating female standoff or threaded hole, while the internal female thread accepts a screw or the next standoff in a stack. It is appropriate wherever a clean, bright stainless finish is required and where QQ-S-763 compliance is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM3x0.5 thread on both male and female ends for metric PCB stacking\u003c\/li\u003e\n\u003cli\u003e303 stainless steel construction, bright uncoated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eHex body shape, 4.50 mm across flats, compatible with standard hex drivers and wrenches\u003c\/li\u003e\n\u003cli\u003eOverall length of 15.76 mm with a body length of 11.00 mm and thread length of 4.76 mm\u003c\/li\u003e\n\u003cli\u003eMeets QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.150 to 0.150 mm for precise board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for metric M3x0.5 threaded circuit board mounting applications in control panels and PCB assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or licensed electricians working on control panel assemblies. De-energize all circuits and discharge any capacitors before handling PCBs or installing standoffs. Use a properly sized hex driver or nut driver matching the 4.50 mm across-flats dimension to avoid rounding the hex body. Apply only hand-tight torque unless a specific torque value is provided by the board or enclosure manufacturer, as over-tightening can stress PCB mounting holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3x0.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male and Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 15.76 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 11.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 4.76 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 6.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel, Grade 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.150 to 0.150 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\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: 0.00488 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: MMF1313M09F16M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51741623189810,"sku":"MMF1313M09F16M3","price":20.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_5220abca-46e0-4996-99c6-ffd12b7ca4bd.jpg?v=1788832548","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1313m09f16m3-hex-standoff-m3x0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
