The standoff features a 2-56 thread size with a male thread on one end and a female thread on the other, allowing boards to be stacked or mounted to a chassis at a fixed, repeatable height. The body is brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. Overall body length is 0.2813 inches with a hex width across flats of 0.1875 inches. Licensed electronics technicians, control board assemblers, and HVAC service technicians use these standoffs when servicing or replacing control boards in residential and light commercial equipment.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for applications where small-format circuit boards require rigid mechanical support and precise separation from a mounting surface or adjacent board. The 2-56 thread size is common in compact control board assemblies found in HVAC equipment, low-voltage control panels, and other electronic enclosures. The hex body allows installation and removal with standard hex drivers or small nutdrivers without marring adjacent components. The zinc plating provides corrosion resistance appropriate for indoor control environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female configuration enables board stacking or chassis mounting in a single fastener\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22\u003c\/li\u003e\n\u003cli\u003e2-56 thread size fits standard small-format circuit board mounting holes\u003c\/li\u003e\n\u003cli\u003eHex body shape allows tool-driven installation with a nutdriver or hex wrench\u003c\/li\u003e\n\u003cli\u003eOverall body length of 0.2813 inches suits compact, low-profile board mounting\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.005 to 0.005 inches ensures consistent board standoff height\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 2-56 male-female hex circuit board standoff for use in printed circuit board assemblies requiring inch-series hardware in compact control enclosures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician following applicable control board service procedures. De-energize all circuits before handling circuit boards or installing standoffs. Use a properly sized nutdriver or hex tool to avoid stripping the hex body. Do not overtighten, as brass standoffs in small thread sizes are susceptible to thread damage if torque is applied beyond snug-fit engagement.\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\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Body Length\u003c\/strong\u003e: 0.2813 inches (9\/32 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 Length\u003c\/strong\u003e: 5\/32 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\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: 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: 0.12 pounds\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: 1306M03F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51730009784626,"sku":"1306M03F21256","price":31.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2ed038b6de2684c05119d308ef78b1d_68eb000f-91fc-4ff3-8a4b-1f2d527f9a2f.jpg?v=1788710117","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1306m03f21256-hex-board-standoff","provider":"Voomi Supply","version":"1.0","type":"link"}
