It features a 1-8 UNC thread size with a 13-inch length under the head and accepts a 3\/4-inch hex drive. The fastener is manufactured from alloy steel with a black oxide coating, which provides moderate corrosion resistance and reduces light glare on exposed surfaces. This screw is partially threaded, allowing it to clamp mating materials without thread engagement in the shank area. It meets ASME\/ANSI B18.3 and ASTM A574 standards, which are common requirements in precision mechanical and industrial installations.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for heavy-duty bolted assemblies where a recessed hex drive is required for torque application in tight or countersunk locations. Typical applications include machine frames, fixtures, tooling plates, and structural steel assemblies in industrial and manufacturing environments. The 1-8 UNC coarse thread pitch performs reliably in standard-tolerance steel and cast-iron bores. The long 13-inch under-head length accommodates deep clamping of thick stacks or long-reach fastening scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-8 UNC coarse thread for reliable engagement in standard steel and cast-iron applications\u003c\/li\u003e\n\u003cli\u003e13-inch length under head accommodates deep assemblies and thick material stacks\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex socket drive for high-torque installation with standard hex keys or socket tooling\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated to ASTM A574 for high tensile and proof load requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and surface hardness\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank allows positive clamping between mating components\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 industrial fastening applications requiring a 1-8 UNC thread form and a 3\/4-inch internal hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by millwrights, maintenance technicians, or mechanical assemblers using a calibrated torque wrench with a 3\/4-inch hex bit or Allen key. Always de-energize and lock out equipment before installing or removing fasteners in live machinery. Verify thread engagement depth and confirm mating hole tolerances conform to ASME standards before final torque. Do not use impact tools without confirming appropriate torque limits for the assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 13 inches\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\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\u003eWeight\u003c\/strong\u003e: 9.93 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: 581824BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717504827698,"sku":"581824BR","price":77.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_efbdb2d0-1e7e-49c6-b4fa-d552485800d7.jpg?v=1788541670","url":"https:\/\/voomisupply.com\/products\/value-collection-581824br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
