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 ends  -  a male post on one side and a female threaded bore on the other  -  allowing standoffs to be threaded together or secured to a chassis. Overall length is 12.76 mm (0.50 inches), body length is 8.00 mm (0.31 inches), and the hex body measures 4.50 mm (0.18 inches) across flats. Electronics assemblers and field technicians use this hardware during board mounting and chassis assembly.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for metric-threaded PCB assembly applications where corrosion resistance and dimensional accuracy are required. The stainless steel construction makes it appropriate for environments where standard zinc or steel hardware would degrade. The male-female configuration is commonly used in multi-board stacking assemblies, control panels, and enclosure builds across industrial, HVAC control, and electronic equipment manufacturing settings. Length tolerance is held to -0.150 to 0.150 mm, making it reliable for precision board-to-board spacing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM3x0.5 male-female thread configuration for stackable PCB mounting\u003c\/li\u003e\n\u003cli\u003e303 stainless steel construction with bright uncoated finish per QQ-S-763\u003c\/li\u003e\n\u003cli\u003eHex body at 4.50 mm across flats for standard hex driver installation\u003c\/li\u003e\n\u003cli\u003eOverall length 12.76 mm with tight length tolerance of -0.150 to 0.150 mm\u003c\/li\u003e\n\u003cli\u003eFemale thread depth of 6.40 mm; male thread length of 4.76 mm\u003c\/li\u003e\n\u003cli\u003eBody length of 8.00 mm provides controlled PCB standoff spacing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M3x0.5 metric-threaded fastener systems in PCB standoff and chassis mounting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand or with a hex driver sized for 4.50 mm across flats. Power down all equipment and discharge any capacitors before working inside a control panel or enclosure. Do not overtighten  -  stainless fasteners are susceptible to galling if driven without proper lubrication or care. Minimum order quantity for this part is 10 pieces.\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: 12.76 mm (0.50 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 8.00 mm (0.31 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\u003c\/strong\u003e: 4.76 mm (0.19 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth (Female)\u003c\/strong\u003e: 6.40 mm (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm (0.18 inches)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\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\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00408 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: MMF1307M09F16M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743002329394,"sku":"MMF1307M09F16M3","price":59.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_1c2236dc-1482-45dc-859f-7b8cdef78e05.jpg?v=1788841435","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1307m09f16m3-hex-standoff-m3x0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
