Built from 303 stainless steel with a bright uncoated finish, this metric fastener uses an M3x0.5 thread on both ends. The overall length is 23.76 mm, the body length is 19.00 mm, and the hex body measures 4.50 mm across flats. The male thread length is 4.76 mm and the female thread depth is 6.40 mm, providing a secure engagement for standard M3 hardware. Licensed electricians, electronics technicians, and instrumentation professionals use this standoff in control panel assemblies, embedded systems, and industrial enclosures.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric PCB mounting applications in both commercial and industrial environments. Typical installations include multi-board stacking configurations, control board mounting inside HVAC units, and DIN-rail mounted electronics assemblies. The stainless steel construction makes it appropriate for environments where corrosion resistance or cleanliness standards are a factor. It conforms to fastener standard QQ-S-763, which covers stainless steel hardware for industrial and mil-spec adjacent applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3x0.5 male-female thread configuration for board-to-board or board-to-panel standoff mounting\u003c\/li\u003e\n  \u003cli\u003e303 stainless steel construction with bright uncoated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHex body at 4.50 mm across flats allows wrench installation and precise torque control\u003c\/li\u003e\n  \u003cli\u003eOverall length of 23.76 mm with a 19.00 mm hex body for consistent board spacing\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 fastener standard for stainless steel hardware\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.150 to 0.150 mm for tight dimensional control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style metric standoff for PCB and panel mounting applications requiring M3x0.5 thread engagement and a 4.50 mm hex body profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or electricians during board assembly or enclosure build-out. Always de-energize and discharge the board or assembly before installing or removing standoffs near live circuits. Use an appropriate metric hex driver or wrench sized for 4.50 mm across flats to avoid rounding the hex body. Do not over-torque the male thread engagement into threaded inserts or PCB hardware, as M3 fasteners have limited thread engagement depth.\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 and Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 23.76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 19.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\u003c\/strong\u003e: 4.76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth (Female)\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\u003eLength Tolerance\u003c\/strong\u003e: -0.150 to 0.150 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 303 Stainless Steel\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: 0.00696 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: MMF1329M09F16M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743182717234,"sku":"MMF1329M09F16M3","price":77.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_642ee2d1-7a58-446b-9007-558d692d8621.jpg?v=1788843642","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1329m09f16m3-hex-standoff-m3x0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
