Machined from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides reliable electrical isolation and mechanical support in control boards, industrial enclosures, and HVAC equipment electronics. The M3 x 0.5 thread on both the male pin and female threaded bore allows secure fastening without cross-threading. Overall length is 17.76 mm (approximately 0.699 inches) with a hex body width across flats of 4.50 mm (approximately 0.177 inches).\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in residential and light commercial control board assemblies, including HVAC system control boards, motor drive electronics, and general electronic panel fabrication. The hex body shape allows a standard hex driver or pliers to apply consistent torque during installation. Technicians working on circuit board replacements, panel builds, or custom enclosure assemblies will find this fastener compatible with standard M3 metric hardware throughout the assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 male-female thread configuration for stackable PCB mounting\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc-plated finish per ASTM B633 Type 1 and QQ-B-626 Comp 22\u003c\/li\u003e\n  \u003cli\u003eHex body shape at 4.50 mm width across flats for wrench or driver installation\u003c\/li\u003e\n  \u003cli\u003eOverall length of 17.76 mm with a length tolerance of -0.150 to 0.150 mm for precise board spacing\u003c\/li\u003e\n  \u003cli\u003eThread depth of 6.40 mm on the female end; thread length of 4.76 mm on the male pin\u003c\/li\u003e\n  \u003cli\u003eMetric measurement system; UNSPSC code 31161816\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a metric M3 x 0.5 male-female hex standoff for use with standard M3 metric circuit board fastening applications in electronic enclosures and control panel assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or field service engineers using a hex driver, nut driver, or appropriately sized pliers sized to 4.50 mm across flats. De-energize and discharge all circuits before working on any control board assembly. Do not over-torque the male pin into mating threads, as brass fasteners are susceptible to thread galling under excessive force. Follow applicable enclosure and panel-build standards for your jurisdiction when mounting control boards in HVAC or electrical equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3 x 0.5\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: 17.76 mm (0.699 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 13.00 mm (0.512 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\u003c\/strong\u003e: 4.76 mm (0.187 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth (Female)\u003c\/strong\u003e: 6.40 mm (0.252 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm (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: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B633 Type 1, QQ-B-626 Comp 22\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: 0.00576 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: MMF1319M03F21M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739843428658,"sku":"MMF1319M03F21M3","price":21.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69e4e1227393bf65cac756010f168c99.jpg?v=1788819512","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1319m03f21m3-hex-standoff-m3x0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
