This screw features a 1-1\/2-6 UNC thread size with a 20-inch length under the head and is partially threaded for controlled engagement in bolted joint applications. It is driven with a 1-inch hex key and is manufactured from alloy steel with a black oxide finish that provides corrosion resistance in moderate environments. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding load-bearing installations. It is typically installed by maintenance technicians, machinists, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is suited for heavy industrial equipment assembly, large-format structural connections, and machinery maintenance where high tensile strength and precise torque control are required. The partial threading allows the unthreaded shank to bear shear loads, which is a common requirement in machinery and equipment frames. The large 1-1\/2-6 UNC thread profile is typical in applications that demand robust clamping force across thick or wide workpieces.\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 applications\u003c\/li\u003e\n  \u003cli\u003e20-inch length under head accommodates thick workpiece stacks\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank distributes shear loads along the bolt body\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers high tensile and yield strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 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 hex socket cap screw for use in tapped holes or with appropriate hex nuts in industrial and mechanical assemblies requiring 1-1\/2-6 UNC threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified machinists or mechanical contractors using a 1-inch hex key or socket driver of adequate length for the 20-inch shank. De-energize, depressurize, or lock out the relevant equipment per OSHA lockout\/tagout requirements before fastener installation or removal. Apply a compatible thread lubricant or anti-seize compound on alloy steel fasteners in environments prone to galling. Do not exceed the rated tensile load for the fastener grade as defined by ASTM A574.\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: 20 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 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 581227BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717683937586,"sku":"581227BR","price":151.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c6bbade592cc1aa33e346e6edbfbdbb.jpg?v=1788544379","url":"https:\/\/voomisupply.com\/products\/value-collection-581227br-hex-socket-cap-screw-1-1-2-6-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
