The standoff features a 2-56 threaded male end on one side and a 2-56 threaded female end on the other, allowing boards to be stacked or mounted with a consistent, secure gap. The hexagonal body measures 3\/16 inches across flats and has an overall body length of 7\/16 inches (0.4375 inches). Constructed from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff delivers corrosion resistance and reliable electrical isolation in panel builds, control board assemblies, and industrial enclosures.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in low-voltage control panels, HVAC control board assemblies, electrical enclosures, and general electronic equipment where precise PCB spacing is required. Electricians, electronics technicians, and panel builders install this type of hardware during new assembly or repair work. The 2-56 thread size targets small-format circuit boards typical in residential and light commercial control applications. The zinc-plated brass construction makes it appropriate for indoor environments where mild corrosion resistance is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female hex configuration allows stacking or surface-mount PCB installation in a single fastener\u003c\/li\u003e\n\u003cli\u003e2-56 thread size on both male and female ends for standard small-board compatibility\u003c\/li\u003e\n\u003cli\u003eHexagonal body at 3\/16 inches across flats for wrench-driven installation and consistent torque\u003c\/li\u003e\n\u003cli\u003eOverall length of 7\/16 inches (0.4375 inches) provides a fixed standoff gap between mating surfaces\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards\u003c\/li\u003e\n\u003cli\u003eThread depth of 3\/16 inches and thread length of 5\/32 inches for secure fastener engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 2-56 male-female hex standoff for use in circuit board assemblies, electronic enclosures, and control panel builds requiring inch-series threaded hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians, electronics technicians, or panel builders using a hex wrench or nut driver sized to the 3\/16-inch flats. Power must be removed from any assembly before installing or removing standoffs near energized components. Avoid overtightening, as brass hardware can strip or crack PCB mounting holes. Follow applicable NEC guidelines and equipment manufacturer torque requirements when installing hardware in listed electrical enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male and Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Body Length\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5\/32 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: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\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: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: 1311M03F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51736722669874,"sku":"1311M03F21256","price":31.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2ed038b6de2684c05119d308ef78b1d_73c734e0-98ed-49a5-9c84-2cc055e0323e.jpg?v=1788779533","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1311m03f21256-hex-standoff-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
