This fastener has a 1-1\/2-6 UNC thread size and measures 16 inches in length under the head, with partial threading along the shank. It is driven with a 1-inch hex (Allen) key. The base material is alloy steel finished with a black oxide coating, which provides mild corrosion resistance and reduces surface reflectivity. At 9.4 pounds, this is a large-format fastener typically installed by millwrights, maintenance machinists, or industrial mechanics.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for heavy industrial machinery, structural steel connections, press frames, large fabricated weldments, and equipment bases where high clamping force and a recessed drive are required. The partially threaded shank allows the unthreaded portion to act as a shoulder or alignment feature within bored holes, making it a common choice in fixture and tooling builds. It conforms to ASME\/ANSI B18.3 dimensional standards and meets ASTM A574 mechanical property requirements for socket cap screws.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-6 UNC thread for high clamping load in heavy assemblies\u003c\/li\u003e\n  \u003cli\u003e16-inch length under head with partial threading for shoulder-fit applications\u003c\/li\u003e\n  \u003cli\u003e1-inch hex drive for positive torque transfer with standard Allen tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-reflectance surface\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 compliant socket cap screw for industrial machinery, structural fabrications, and heavy equipment assemblies requiring a 1-1\/2-6 UNC thread form.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified millwrights, machinists, or industrial mechanics using a calibrated torque wrench and the appropriate 1-inch hex key or socket drive. De-energize, lockout, and tag out any equipment before fastener installation or removal per applicable OSHA lockout\/tagout procedures. Inspect mating tapped holes for thread condition and cleanliness before installation. Do not substitute lubricant or thread treatment products unless verified against the design specification, as these affect torque-to-clamp-load values.\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: 16 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\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 581962BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716534567218,"sku":"581962BR","price":110.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_277f228d-07ee-4cb3-a636-4977f5da29d0.jpg?v=1788527467","url":"https:\/\/voomisupply.com\/products\/value-collection-581962br-hex-socket-cap-screw-1-1-2-6-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
