It features a 1\/2-13 UNC thread size with a 2-inch length under head, driven by a 3\/8-inch hex socket drive. Constructed from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and surface hardness. It meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where dimensional accuracy and mechanical strength are required. Licensed trades and maintenance professionals rely on this screw type for reliable clamping force in precision-fit joints.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is suited for use in manufacturing, maintenance, and repair environments where a low-profile, high-torque fastener is needed. The hex drive socket head allows installation in recessed or tight clearance areas where a standard hex head wrench cannot reach. Typical applications include machine frames, fixture plates, jigs, pump housings, and industrial equipment panels. The fully threaded shank engages the full depth of a tapped hole, which is particularly useful in shallow or through-hole configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e2-inch length under head with full threading along the entire shank\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for use with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and reduces light reflection in precision environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket fastener for applications requiring a 1\/2-13 UNC fully threaded socket cap screw in alloy steel. Verify thread pitch, length under head, and drive size against the existing fastener or engineering specification before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 3\/8-inch hex key or socket bit driver. Ensure the mating tapped hole is clean, free of debris, and properly sized for 1\/2-13 UNC thread engagement before driving the fastener. Do not exceed the recommended seating torque for the material being fastened, and apply thread lubricant or anti-seize compound where required by the application. Power down and de-energize any equipment before accessing fastener locations on live machinery.\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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 25\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: 33666\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710606672178,"sku":"33666","price":38.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08e7d4e12438564b782a89a78f2f832b.jpg?v=1788468684","url":"https:\/\/voomisupply.com\/products\/value-collection-33666-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
