It features a 1-1\/2-6 UNC thread form and a 5-inch length under head, with partial threading along the shank. The drive type is hex, accepting a 1-inch hex key or Allen wrench. Constructed from alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance in controlled environments. It conforms to ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for precision-load applications where dimensional and strength compliance is required.\u003c\/p\u003e\u003cp\u003eThis screw is appropriate for use in machine assembly, heavy equipment fabrication, tooling fixtures, and structural bolted connections where a recessed drive is preferred. The partial thread configuration is standard for longer-length cap screws, allowing the unthreaded shank to bear shear loads while the threaded portion engages the tapped hole. Machinists, millwrights, maintenance technicians, and mechanical contractors commonly specify this type of fastener. Its large 1-1\/2-inch diameter makes it well suited for high-clamping-force applications in steel-to-steel joints.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/2-6 UNC thread size for high-strength bolted joints\u003c\/li\u003e\n\u003cli\u003e5-inch length under head with partial threading for shear-load-bearing shank\u003c\/li\u003e\n\u003cli\u003e1-inch hex drive accepts standard hex keys and Allen drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in tapped holes with 1-1\/2-6 UNC internal threads in steel, cast iron, or other compatible base materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical technician using a properly sized 1-inch hex key or torque wrench with a hex bit. Verify that the receiving tapped hole matches the 1-1\/2-6 UNC thread specification before installation. Clean threads and apply appropriate thread lubricant or anti-seize compound as required by the application to achieve accurate clamp load. Always torque to the value specified by the equipment manufacturer or applicable engineering standard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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 Coating\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 011591BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722090971442,"sku":"011591BR","price":114.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_3ba3c944-9745-4abb-b82e-cda659832d1c.jpg?v=1788585519","url":"https:\/\/voomisupply.com\/products\/value-collection-011591br-hex-socket-cap-screw-1-1-2-6-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
