The standoff features an M3x0.5 male thread on one end and an M3x0.5 female thread on the other, allowing boards to be secured and spaced in a single fastener pass. Constructed from 303 stainless steel with a bright uncoated finish, it meets the QQ-S-763 fastener standard. The hex body profile allows for wrench engagement during installation. Overall length is 11.76 mm (approximately 0.463 inches), with a body length of 7.00 mm and a thread depth of 6.40 mm on the female end.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in electronics assemblies requiring corrosion-resistant hardware, including control boards found in HVAC equipment, industrial enclosures, and commercial electrical panels. The metric M3x0.5 thread size makes it appropriate for PCB mounting applications following metric fastener conventions. Technicians and electronics assemblers working on board-level repairs or custom enclosure builds will find this standoff useful wherever rigid, repeatable board-to-board or board-to-chassis spacing is required. The stainless steel construction resists oxidation in environments with elevated humidity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3x0.5 male-female thread configuration for stackable PCB mounting\u003c\/li\u003e\n  \u003cli\u003e303 stainless steel construction meets QQ-S-763 standard\u003c\/li\u003e\n  \u003cli\u003eHex body at 4.5 mm width across flats allows wrench or nut-driver installation\u003c\/li\u003e\n  \u003cli\u003eOverall length of 11.76 mm with a length tolerance of -0.150 to 0.150 mm for precise board spacing\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains dimensional accuracy without coating buildup on threads\u003c\/li\u003e\n  \u003cli\u003eLightweight at approximately 0.00384 pounds per piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-use hex standoff for circuit board assemblies requiring M3x0.5 metric thread fasteners with a 4.5 mm hex body profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or field service engineers working on PCB assemblies. De-energize all boards and discharge any capacitors before handling circuit board hardware. Use an appropriately sized nut driver or hex wrench sized for a 4.5 mm across-flats hex body to avoid rounding the standoff during tightening. Do not over-torque the M3 threads, as stainless steel fasteners in close-tolerance metric threads are susceptible to galling.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male-Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 11.76 mm (approximately 0.463 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 7.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth (Female End)\u003c\/strong\u003e: 6.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length (Male End)\u003c\/strong\u003e: 4.76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm (approximately 0.177 inches)\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: 0.00384 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: MMF1305M09F16M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740935782706,"sku":"MMF1305M09F16M3","price":20.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_c20c3157-0951-4b88-963f-fd0c13fb91df.jpg?v=1788828469","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1305m09f16m3-hex-standoff-m3x0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
