The standoff features a 2-56 thread size with a male thread on one end and a female threaded bore on the other, allowing boards to be stacked or mounted at a fixed distance from a panel or chassis. The body is steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards. The overall length is 2.5 inches, the width across flats is 0.1875 inches (3\/16 inches), and the thread depth is 3\/16 inches. These standoffs are installed by electronics technicians and control board assemblers in commercial and industrial applications.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in control panel assemblies, HVAC control boards, electrical enclosures, and other applications where circuit boards require rigid, fixed-height mounting. The hex body shape allows installation and removal with standard hex drivers or nut drivers. The zinc plating provides corrosion resistance for indoor and light-duty environments. Its 2-56 thread size fits standard 2-56 machine screw hardware commonly used in PCB mounting applications across residential and commercial electronic controls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female configuration allows PCB stacking or chassis mounting in a single standoff\u003c\/li\u003e\n\u003cli\u003e2-56 thread size compatible with standard PCB mounting hardware\u003c\/li\u003e\n\u003cli\u003eHex body shape accepts nut driver or hex wrench for installation and removal\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-S-633 standards\u003c\/li\u003e\n\u003cli\u003eOverall length of 2.5 inches provides consistent board-to-surface spacing\u003c\/li\u003e\n\u003cli\u003eThread length of 5\/32 inches on the male end with 3\/16-inch thread depth on the female end\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for circuit board assemblies using 2-56 machine screw hardware in control panels, HVAC boards, and electronic enclosures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics technicians or licensed electricians during control board assembly or replacement. Power down and de-energize the equipment fully before working on any circuit board assembly. Use a appropriately sized nut driver or hex wrench on the 3\/16-inch across-flats body to avoid rounding the hex. Follow applicable NEC guidelines when installing standoffs inside electrical enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male-Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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\u003eThread Depth (Female)\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\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\u003eBody Length\u003c\/strong\u003e: 2.5 inches\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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 2\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-S-633\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1377M12F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51750646251826,"sku":"1377M12F21256","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354e84e78593c87d91054c55b2ccfd1d_cf302fc6-fd65-4602-99dc-e2b282ee74bd.jpg?v=1788917742","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1377m12f21256-hex-standoff-2-56-2-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
