It features a 1-8 UNC thread size with a 4-inch length under head, providing deep engagement for secure clamping in thick material stacks. The screw is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces surface reflectivity. Drive size is 3\/4 inch hex, requiring a standard hex key or Allen-type driver. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding structural and machine-element fastening tasks.\u003c\/p\u003e\u003cp\u003eThis cap screw is used in general industrial maintenance, machine building, die and mold work, and heavy equipment assembly. The 1-8 UNC coarse thread and 4-inch under-head length make it a common choice when fastening thick flanges, brackets, or machine bases where a flush or recessed head profile is required. Mechanical maintenance technicians, machinists, and industrial assembly crews are the primary installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-8 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e4-inch length under head allows fastening through thick material stacks\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a smooth bearing surface for shear-load applications\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction delivers high tensile strength per ASTM A574\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex drive fits standard hex keys and socket drivers\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1-8 UNC hex socket cap screw suitable for any tapped hole or nut conforming to 1-8 UNC thread form per ASME\/ANSI B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical technician using a calibrated hex key or torque wrench with the appropriate 3\/4-inch hex bit. Always verify that the mating tapped hole thread form and depth are compatible before driving the fastener. De-energize, de-pressurize, or otherwise make safe any equipment before fastener installation or removal. Do not exceed the rated torque for the fastener grade as stamped or referenced in the applicable engineering specification.\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: 4 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\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\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: -33715-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689333457202,"sku":"-33715-1","price":62.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b1f120d2252eb3c372a8e4ae205f715.jpg?v=1788257729","url":"https:\/\/voomisupply.com\/products\/value-collection-33715-1-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
