It features a 3\/8-16 UNC thread form and measures 1-1\/4 inches under the head. The 9\/16-inch hex drive size is compatible with standard wrenches and sockets. This fastener is suited for applications where weight reduction and moderate strength are priorities, such as mechanical assemblies, structural brackets, and equipment enclosures. Installers and maintenance technicians working in aerospace-adjacent, HVAC equipment, or light structural fabrication environments will find this grade appropriate where steel corrosion is a concern but tensile load demands remain within the limits of aluminum alloy fasteners.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in inch-system assemblies calling for a 3\/8-16 UNC thread. Typical installations include bolted joints in aluminum frames, access panel mounting, and light mechanical sub-assemblies. The 2024T4 material grade offers higher strength than standard 6061 aluminum, making it a common choice when the joint demands more than a general-purpose aluminum fastener can provide. Sold individually per package, with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2024T4 aluminum alloy construction for elevated strength-to-weight ratio\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for compatibility with standard inch-system tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head suits a range of joint stack thicknesses\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch hex drive accepts standard wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eAluminum material reduces galvanic and oxidation concerns in compatible assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in inch-system assemblies requiring a 3\/8-16 UNC hex head cap screw in aluminum.

De-energize and depressurize any system before accessing the joint being fastened. Aluminum fasteners are more susceptible to galling than steel; apply an appropriate anti-seize compound when threading into aluminum tapped holes. Follow applicable torque specifications from the equipment OEM or relevant structural code for 3\/8-16 aluminum fasteners, as no torque value was provided with this part.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Drive Size\u003c\/strong\u003e: 9\/16 inches\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: 2024T4\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: 10\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3720CHAL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722561323314,"sku":"3720CHAL","price":2633.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cd11bf7afa317345a8c8df8659948c0.jpg?v=1788592843","url":"https:\/\/voomisupply.com\/products\/value-collection-3720chal-hex-head-cap-screw-3-8-16-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
