Machined from brass with a clear zinc chromate finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff accepts a 2-56 threaded fastener and provides a fully threaded internal bore with a thread depth of 3\/16 inches. The overall length is 3\/16 inches and the hex body measures 3\/16 inches across the flats. Electronics technicians and electrical assemblers install these standoffs during PCB assembly and enclosure builds where controlled board-to-surface clearance is required.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in low-voltage electronic assemblies, control panels, HVAC control boards, and similar applications where a compact 2-56 threaded female standoff is specified. The small form factor makes it appropriate for tight-clearance board layouts in residential and light commercial equipment. Its fully threaded bore allows a machine screw to engage the full thread depth, providing secure fastener retention in vibration-prone environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale hex body style with fully threaded internal bore for secure screw engagement\u003c\/li\u003e\n  \u003cli\u003e2-56 thread size for compatibility with standard small-fastener PCB hardware\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch overall length with a length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eBrass construction with clear zinc chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 fastener standards\u003c\/li\u003e\n  \u003cli\u003eHex body shape allows installation and removal with standard hex drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 2-56 female hex circuit board standoff for use in PCB mounting applications that require an inch-measurement fastener system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or electrical assemblers during board-level assembly or control panel wiring. De-energize all circuits before servicing any control board or enclosure. Use a hex driver or socket sized for 3\/16 inch across-flats to seat the standoff without rounding the hex body. Avoid over-torquing, as brass fasteners are susceptible to thread damage under excessive load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3\/16 inches (0.1875 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 Length\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inches (0.1875 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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: P289M03F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51737269076274,"sku":"P289M03F21256","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69be0ea513ec4cbce20afd5016302ef1_b526590e-b626-41f1-a453-51ad5d645804.jpg?v=1788786415","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p289m03f21256-hex-standoff-2-56-3-16in","provider":"Voomi Supply","version":"1.0","type":"link"}
