It accepts a 4-40 thread and measures 0.75 inches overall length with a 0.25-inch width across flats on a hex body profile. Standoffs of this type are used to create a fixed, electrically isolated gap between a PCB and a chassis or between stacked boards. The material grade is T-3 aluminum, and the part conforms to the QQ-A-225A Comp 2 fastener standard. Installation is typically performed by electronics technicians, panel builders, and field service technicians working on control boards in HVAC, electrical, and industrial equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in control panel assemblies, PCB mounting applications, and equipment enclosures where a lightweight, corrosion-resistant spacer is required. It is appropriate for both residential and light commercial equipment applications, including control board mounting in HVAC equipment, electrical panels, and other enclosures where 4-40 threaded fasteners are specified. The hex body allows for wrench engagement during installation, providing precise torque control without spinning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale 4-40 threaded interior for standard PCB mounting hardware\u003c\/li\u003e\n  \u003cli\u003e0.75-inch overall length provides consistent board standoff height\u003c\/li\u003e\n  \u003cli\u003e0.25-inch hex body width across flats allows wrench or nut driver engagement\u003c\/li\u003e\n  \u003cli\u003eT-3 aluminum construction keeps weight low while maintaining structural integrity\u003c\/li\u003e\n  \u003cli\u003eAnodized bright finish provides corrosion resistance in enclosed environments\u003c\/li\u003e\n  \u003cli\u003eConforms to QQ-A-225A Comp 2 fastener standard for verified material quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for any circuit board assembly using 4-40 threaded hardware and requiring a 0.75-inch standoff height with a hex body profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or qualified trade professionals during control board assembly or replacement. Power down all equipment and discharge any capacitors before working on PCB assemblies. A nut driver or small wrench sized to 0.25 inches across flats should be used to seat the standoff without overdriving. Follow the equipment manufacturer's torque guidance and applicable electrical codes when mounting control boards in enclosures.\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: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.25 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: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Anodized Bright\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\u003eStandard\u003c\/strong\u003e: QQ-A-225A Comp 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: P545M06F16-440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739869086002,"sku":"P545M06F16-440","price":21.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f50a98d39facb4d531f6bac320a20c0a.jpg?v=1788819856","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p545m06f16-440-hex-standoff-4-40-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
