The standoff features a 2-56 unified thread on both the male and female ends, a hex body measuring 3\/16 inches across the flats, and an overall body length of 1-1\/4 inches. Constructed from steel with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-S-633 standards, this fastener is suited for electronics assembly, panel builds, and control board mounting in HVAC, electrical, and industrial enclosure applications.\u003c\/p\u003e\u003cp\u003eThis standoff is used in applications where circuit boards require secure, elevated mounting with a threaded male post on one end for stacking or attaching hardware and a threaded female receiver on the other end for accepting a mating screw or standoff. Typical install scenarios include control board mounting inside HVAC equipment, electrical panels, and industrial enclosures. The inch-system thread sizing and standard hex body make it compatible with common 2-56 fastener assemblies used across light-duty electronics and control board work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female configuration allows stacking of boards or mixed fastener attachment at each end\u003c\/li\u003e\n\u003cli\u003e2-56 unified thread on both ends with a thread depth of 3\/16 inches and thread length of 5\/32 inches\u003c\/li\u003e\n\u003cli\u003eHex body profile at 3\/16 inches across the flats allows standard nut driver or hex tool installation\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel construction meets ASTM B633 Type 1 and QQ-S-633 corrosion-resistance standards\u003c\/li\u003e\n\u003cli\u003eOverall body length of 1-1\/4 inches provides consistent PCB standoff height for controlled board clearance\u003c\/li\u003e\n\u003cli\u003eLength tolerance held to plus or minus 0.005 inches for precise assembly fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install fastener for 2-56 threaded circuit board standoff applications in inch-system assemblies, including control board mounting in residential and light commercial HVAC, electrical enclosures, and general electronics panel builds.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electricians, electronics technicians, or HVAC controls technicians. De-energize all equipment and discharge any capacitors before handling circuit boards or control assemblies. Use a correctly sized nut driver or hex tool matching the 3\/16-inch across-flats dimension to avoid rounding the hex body. Follow applicable NEC guidelines when mounting control boards inside 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 Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody 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\u003eThread Length\u003c\/strong\u003e: 5\/32 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\u003eBody Shape\u003c\/strong\u003e: Hex\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: 1337M12F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51755419402546,"sku":"1337M12F21256","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354e84e78593c87d91054c55b2ccfd1d_1f18dc39-93b2-4f50-87f1-e46771c366d1.jpg?v=1788954843","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1337m12f21256-hex-standoff-2-56-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
