The body is machined from brass with a clear zinc chromate finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. It features a 2-56 female thread, an overall length of 0.5 inches, and a width across flats of 0.1875 inches (3\/16 inches). The fully threaded interior accepts a 2-56 male fastener to the full thread depth of 0.5 inches. Electronics technicians, PCB assembly professionals, and HVAC controls installers use this standoff wherever board-to-board or board-to-chassis separation is required.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in low-voltage control board assemblies, industrial electronics enclosures, and instrument panels. Its compact 0.1875-inch hex body fits into tight board layouts where clearance is limited. The brass base material offers good conductivity and corrosion resistance, making it appropriate for both indoor control panel assemblies and electronics manufacturing environments. It is sold and packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale 2-56 thread, fully threaded to 0.5 inches depth\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.5 inches with a length tolerance of -0.005 to +0.005 inches\u003c\/li\u003e\n\u003cli\u003eHex body shape, 0.1875 inches (3\/16 inches) width across flats\u003c\/li\u003e\n\u003cli\u003eBrass construction with clear zinc chromate finish\u003c\/li\u003e\n\u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards\u003c\/li\u003e\n\u003cli\u003eInch measurement system; UNSPSC Code 31161816\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install hex standoff for circuit board assemblies using 2-56 inch-series fasteners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or controls professionals. Power down and de-energize any circuit board assembly before installing or removing standoffs. Use an appropriately sized hex driver or nut driver to avoid rounding the 0.1875-inch flats. Ensure mating fasteners are 2-56 thread to prevent cross-threading or stripping the brass body.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: 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 Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\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: -0.005 to +0.005 inches\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: Clear Zinc Chromate\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: P309M03F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51752200569138,"sku":"P309M03F21256","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69be0ea513ec4cbce20afd5016302ef1_e70da8f5-6d9b-469c-befe-ad00c21e55db.jpg?v=1788926527","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p309m03f21256-hex-standoff-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
