This standoff features a 4-40 thread size with a fully threaded female interior and a 1\/4 inch thread depth. The hex body measures 3\/16 inch across flats and an overall length of 1\/4 inch. Constructed from brass with a clear zinc chromate finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, it provides corrosion resistance appropriate for industrial and commercial electronic applications. Electricians, control panel builders, and electronics technicians use these standoffs during board installation and enclosure assembly.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in residential and commercial control panel assemblies, HVAC system boards, electrical enclosures, and general electronics mounting applications where 4-40 threaded brass hardware is specified. The hex body allows for easy installation and removal with standard hex drivers or wrenches. A minimum order quantity of 10 units applies, making this part appropriate for service stock or panel builds requiring consistent hardware across multiple boards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale 4-40 threaded interior with 1\/4 inch full thread depth for secure board fastening\u003c\/li\u003e\n  \u003cli\u003eHex body profile at 3\/16 inch across flats allows wrench or driver engagement\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\u003eCompact 1\/4 inch overall length suits tight PCB spacing requirements\u003c\/li\u003e\n  \u003cli\u003eLength tolerance held to -0.005 to 0.005 inch for consistent board standoff height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service stock standoff for applications requiring 4-40 female threaded brass hex standoffs with a 1\/4 inch overall length in circuit board mounting configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed electricians or electronics technicians during panel assembly or board replacement. De-energize all equipment and discharge any stored energy before working inside enclosures. Use an appropriately sized hex driver or nutdriver to engage the 3\/16 inch across-flats body without over-torquing the brass threads. Follow applicable NEC guidelines for enclosure work and consult the board or enclosure manufacturer documentation for specified standoff height and thread requirements.\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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 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\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: P293M03F21440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51732885897522,"sku":"P293M03F21440","price":21.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40416b0e5d46d188698579b2cebf876b.jpg?v=1788748065","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p293m03f21440-hex-standoff-4-40-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
