Sized at 1-1\/2-6 UNC thread with a 5-inch length under head, this fastener is partially threaded and accepts a 1-inch hex drive. It is manufactured from alloy steel with a black oxide coating that provides moderate corrosion resistance and reduces surface reflectivity. This screw meets ASME B18.3 and ASTM A574 standards, making it appropriate for structural and mechanical assemblies where dimensional and material compliance is required by spec.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial, mechanical, and structural applications where large-diameter, high-strength fasteners are required. Typical installations include heavy machinery frames, fabricated steel assemblies, jig and fixture construction, and equipment mounting applications. The partially threaded shank provides a bearing surface that resists shear loading, which is an important consideration in bolted joint design. Licensed tradespeople and industrial maintenance technicians are the primary installers of hardware at this size class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-6 UNC thread size for heavy-duty clamping force\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head with partial threading for shear-load resistance\u003c\/li\u003e\n  \u003cli\u003e1-inch hex socket drive for use with standard hex keys or drive tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion protection and low-glare surface\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement hex socket cap screw for industrial and structural bolted assemblies requiring a 1-1\/2-6 UNC partially threaded fastener conforming to ASME B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of large-diameter socket cap screws at this size class typically requires a calibrated torque wrench and a 1-inch hex key or drive socket to achieve proper clamp load. Power down or de-energize any equipment before replacing fasteners in live assemblies. Ensure mating threads are clean and free of debris before installation. Follow applicable ASME or project-specific torque specifications as supplied by the equipment manufacturer or structural engineer of record.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-6 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 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: 1 inch\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\u003eWeight\u003c\/strong\u003e: 3.98 pounds\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72434\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51742015848754,"sku":"72434","price":110.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/755552d3853a5c03f3f2f624aa11033f_ccaf364c-ac92-4209-85d4-2da49124c535.jpg?v=1788834937","url":"https:\/\/voomisupply.com\/products\/holo-krome-72434-hex-socket-cap-screw-1-1-2-6-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
