The screw features a 1-8 UNC thread size and measures 7.5 inches in length under the head, making it suitable for deep-engagement fastening in thick stock or stacked components. Drive type is hex socket at 3\/4 inches, accommodating standard hex keys and socket-drive tools. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and moderate corrosion resistance in controlled environments. Installation is typically performed by machinists, millwrights, maintenance technicians, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a wide range of industrial and mechanical applications including machinery mounting, equipment frames, structural fixtures, and tooling assemblies. The partially threaded shank allows precise bearing-load transfer and accurate axial alignment in bolted joints. The 1-8 UNC coarse thread profile offers reliable engagement in standard tapped holes and threaded inserts. The black oxide coating provides a low-reflectance surface and mild protection against oxidation during storage and service in dry or lightly oiled environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC coarse thread for strong engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e7.5 inches length under head for deep-stack or heavy-material fastening\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch hex socket drive compatible with standard hex keys and socket tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish delivers mild corrosion resistance and low-reflectance appearance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for accurate load transfer and joint alignment\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1-8 UNC hex socket cap screw suitable for use in any tapped hole or threaded assembly conforming to ASME\/ANSI B18.3 and ASTM A574 specifications for alloy steel socket cap screws.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 3\/4 inch hex key or socket-drive tool rated for the applied torque. Ensure the mating tapped hole thread form and depth are clean and free of debris before driving the fastener. Follow applicable machinery safety lockout\/tagout procedures before servicing any assembly. Do not exceed the rated tensile strength of the fastener by applying impact-drive methods without proper tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 7.5 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 Coating\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: 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: 581820BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722218406194,"sku":"581820BR","price":29.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_7a0d09e5-cd38-4c80-acad-c028545378d5.jpg?v=1788587585","url":"https:\/\/voomisupply.com\/products\/value-collection-581820br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
