It features a 4-40 thread size, a 1 inch overall length with 1 inch of full thread depth, and a hexagonal body with a 3\/16 inch width across flats for standard hex tool engagement. Constructed from brass with a clear zinc chromate finish, it meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. This standoff is installed by electronics assemblers, field service technicians, and control board replacement specialists working across HVAC, electrical, and related trade equipment.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for residential and commercial circuit board mounting applications where a threaded female receptacle is required to secure a PCB at a fixed standoff height. Typical installations include control board mounting in HVAC equipment, electrical enclosures, and industrial panel assemblies. The 4-40 thread and 1 inch spacing make it a common choice for light-gauge PCB mounting where consistent board-to-chassis clearance is required. Minimum order quantity is 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale 4-40 thread with 1 inch full thread depth for secure fastener engagement\u003c\/li\u003e\n\u003cli\u003eHexagonal body profile, 3\/16 inch width across flats, accepts standard hex wrench or driver\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\u003e1 inch overall length provides consistent PCB standoff height\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.005 to 0.005 inches for precision mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 female hex standoff for circuit board mounting applications requiring a 1 inch OAL brass hex standoff with clear zinc chromate finish.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or trade professionals during control board mounting or replacement. Power down and de-energize all circuits before working in any enclosure. Use a hex wrench or nut driver sized for 3\/16 inch flats to drive and torque the standoff without damaging the hex body. Avoid over-tightening, which can crack or stress the PCB mounting hole or damage the brass threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inch (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\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\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\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: 1 pound (package)\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: P341M03F21440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51731953484082,"sku":"P341M03F21440","price":29.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69be0ea513ec4cbce20afd5016302ef1_c33e3d79-35ef-4e33-834e-4a8e34b1d128.jpg?v=1788737163","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p341m03f21440-hex-standoff-4-40-1in","provider":"Voomi Supply","version":"1.0","type":"link"}
