It accepts a 2-56 machine screw on both ends, providing a secure female thread connection. The overall length is 1.25 inches, and the hex body measures 3\/16 inches across the flats, allowing standard hex tooling to drive or hold the standoff during installation. The body is machined from brass and finished with a zinc plating that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 specifications for corrosion resistance. This standoff suits electronics assembly and control board mounting work across HVAC, electrical, and industrial panel applications.\u003c\/p\u003e\u003cp\u003eThis standoff is a standard inch-series fastener used wherever a rigid, electrically isolated or grounded spacing post is needed on a circuit board assembly. Common applications include mounting control boards inside HVAC air handlers and furnace cabinets, securing relay boards within electrical enclosures, and building custom panel assemblies. The 2-56 thread size and 1-1\/4 inch body length are frequently encountered in residential and light commercial control board configurations. Installation does not require specialized tooling beyond a standard hex wrench or nut driver sized for 3\/16 inch across flats.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale 2-56 thread accepts standard 2-56 machine screws for secure board-to-board or board-to-chassis mounting\u003c\/li\u003e\n\u003cli\u003e1.25 inch overall length provides precise standoff height between mating surfaces\u003c\/li\u003e\n\u003cli\u003eHexagonal body at 3\/16 inches across flats allows hex wrench or nut driver installation\u003c\/li\u003e\n\u003cli\u003e3\/16 inch thread depth on each end ensures adequate thread engagement for 2-56 fasteners\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc plating meets ASTM B633 Type 1 and QQ-B-626 Comp 22 corrosion resistance standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or general-use standoff for circuit board assemblies requiring a 2-56 inch-series female hex standoff with a 1-1\/4 inch overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics assembly technicians or electricians working on control panel builds. Always de-energize and lock out the equipment before servicing any circuit board or control assembly. Use a properly sized nut driver or hex wrench matching the 3\/16 inch across-flats dimension to avoid rounding the hex body. Do not overtighten — apply only enough torque to seat the standoff firmly against the board surface without cracking the PCB substrate.\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: 1.25 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\u003eThread Depth\u003c\/strong\u003e: 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\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: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: P357M03F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51731758186802,"sku":"P357M03F21256","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69be0ea513ec4cbce20afd5016302ef1_076b82aa-e214-4309-b17f-a1420db79fbf.jpg?v=1788734612","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p357m03f21256-hex-standoff-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
