The standoff features a 4-40 unified coarse thread on both the male and female ends, a hex body shape measuring 3\/16 inches across the flats, and an overall body length of 0.5 inches. Constructed from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, it provides corrosion resistance and reliable conductivity for PCB assembly applications. Minimum order quantity is 10 units.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in the assembly and stacking of printed circuit boards in electronic control panels, HVAC control boards, electrical enclosures, and similar low-voltage electronic assemblies. It is appropriate for residential and light commercial applications where boards require rigid, repeatable spacing. The male stud threads into an existing female receiver on one board while the female end accepts the next fastener or standoff in the stack, allowing modular board configurations. Technicians and panel builders working with 4-40 threaded hardware will find this a straightforward fit for standard PCB layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 unified coarse thread on both male and female ends for standard PCB fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eHex body shape at 3\/16 inches across the flats for wrench or nut-driver installation\u003c\/li\u003e\n  \u003cli\u003eOverall body length of 0.5 inches with a thread depth of 1\/4 inch and thread length of 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish standards\u003c\/li\u003e\n  \u003cli\u003eLength tolerance held to plus or minus 0.005 inches for consistent board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 male-female hex standoff for use in PCB assemblies and electronic enclosures requiring 1\/2-inch board spacing with unified coarse thread fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by panel builders or electronics technicians during board assembly or field replacement of control assemblies. De-energize all circuits completely before working on or near any circuit board. Use a nut driver or small wrench sized for 3\/16-inch hex flats to seat the standoff without over-torquing, which can crack board mounting holes. Ensure mating threads are clean and free of debris before assembly to maintain accurate spacing tolerances.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male and Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 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: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\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: 0.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: 1313M03F21440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51750188482866,"sku":"1313M03F21440","price":19.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2ed038b6de2684c05119d308ef78b1d_1cde051b-5b27-4ff2-af24-d0b0ebbcbc39.jpg?v=1788914211","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1313m03f21440-hex-standoff-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
