It features a 1\/2-13 UNC thread size with a 3-inch length under head and partial threading along the shank. The drive type is a 3\/8-inch hex socket, requiring a standard hex key or Allen driver for installation. Constructed from alloy steel with a black oxide finish, this fastener offers solid mechanical strength and moderate corrosion resistance. It meets ASME B18.3 and ASTM A574 standards. Each package contains 5 screws.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for general industrial maintenance, machine assembly, and fabrication work where a flush or recessed drive head is required. The partial threading provides a grip zone on the shank, making it appropriate for clamping applications where a bearing surface is needed between the threaded and unthreaded portions. It is commonly installed by millwrights, maintenance technicians, and machinists working on equipment frames, tooling fixtures, and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread size with 3-inch length under head\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for clamping and precise fastening\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for use with standard Allen keys or hex drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener specification\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides surface protection and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standard for socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fastener for applications requiring a 1\/2-13 UNC hex socket cap screw with a 3-inch length under head.

Torque to the specification called out in the equipment service documentation — do not substitute torque values from general fastener charts without confirming the joint design. Inspect threads for damage before installation. Black oxide finish is not a heavy corrosion barrier; apply thread-locking compound or anti-seize as appropriate for the environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\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: MP72242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693237600562,"sku":"MP72242","price":23.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d55842a619738750da1fe204ad0ded8.jpg?v=1788309450","url":"https:\/\/voomisupply.com\/products\/value-collection-mp72242-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
