Machined from 303 stainless steel with a bright uncoated finish, this standoff meets the QQ-S-763 fastener standard. The M3x0.5 male thread engages one mounting point while the M3x0.5 female thread receives a mating fastener or the next standoff in a stacked assembly. Overall length is 13.76 mm, body length is 9.00 mm, and the hex body measures 4.50 mm across flats for standard wrench engagement. Licensed electricians, electronics assemblers, and field service technicians install these during control board and panel assemblies.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in residential and commercial control panel assemblies, HVAC circuit board mounting, and industrial electronics enclosures where stainless steel corrosion resistance and a metric M3x0.5 thread form are required. The hex body allows torque to be applied with a standard wrench or hex driver without slipping or marring adjacent board surfaces. It is appropriate wherever a rigid, measured standoff between PCB layers or between a board and a chassis is needed in a metric-fastener assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale M3x0.5 thread on one end, female M3x0.5 thread on the opposite end for stacked or board-to-chassis mounting\u003c\/li\u003e\n  \u003cli\u003e303 stainless steel construction meets QQ-S-763 fastener standard for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHex body profile at 4.50 mm across flats allows standard wrench engagement\u003c\/li\u003e\n  \u003cli\u003eOverall length of 13.76 mm with a body length of 9.00 mm and thread length of 4.76 mm\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.150 to 0.150 mm for consistent stack height in precision assemblies\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish  -  no plating to introduce dimensional variation or corrosion concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in assemblies requiring metric M3x0.5 threaded standoffs with a hex body; fits any application calling for a male-female hex PCB standoff to the QQ-S-763 standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove with an appropriately sized hex wrench or nut driver sized for 4.50 mm across flats. De-energize and discharge all circuits on the control board or panel before handling standoffs in an energized enclosure. Avoid over-torquing the male thread into a tapped PCB boss, as stainless fasteners in close-tolerance metric threads can gall  -  apply consistent, controlled torque. Follow applicable NEC or IPC assembly guidelines for board mounting hardware in the specific panel or enclosure type being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3x0.5 (Male and Female)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 13.76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 9.00 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\u003eLength Tolerance\u003c\/strong\u003e: -0.150 to 0.150 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\u003eFastener Standard\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: 0.00432 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: MMF1309M09F16M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51742218912050,"sku":"MMF1309M09F16M3","price":20.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_8331e538-35c5-4d11-9eca-ce34fe1bd849.jpg?v=1788835956","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1309m09f16m3-hex-standoff-m3x0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
