Machined to Grade 8 steel specifications, this screw carries a thread size of 1-3\/4-5 UNC and measures 4 inches under the head. The partially threaded shank allows the unthreaded portion to bear shear loads, making it well-suited for structural and mechanical assemblies. The bright, uncoated finish is standard for Grade 8 hardware in dry or controlled environments. Mechanical contractors, millwrights, and structural fabricators typically work with fasteners in this size range.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy industrial, structural, and mechanical fabrication environments where high-strength fasteners are required. Grade 8 hardware is commonly specified for machine frames, structural steel connections, heavy equipment mounting, and other applications where fastener yield strength is critical. The UNC thread form is the standard for inch-series fasteners in North American trade and industrial work, and the 1-3\/4-5 designation indicates a coarse-thread pitch appropriate for this diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and yield strength in demanding applications\u003c\/li\u003e\n  \u003cli\u003e1-3\/4-5 UNC coarse thread standard for broad compatibility with inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e4-inch length measured under the head for precise structural fitment\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides an unthreaded grip section to handle shear loads\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suits dry or protected installation environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with 1-3\/4-5 UNC nuts and tapped holes in heavy industrial, structural, and mechanical assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of large-diameter Grade 8 fasteners is typically performed by millwrights, ironworkers, or mechanical contractors using calibrated torque wrenches or impact tooling. Always verify mating nut grade and thread engagement before applying torque. Consult applicable structural or equipment specifications for torque requirements, as no torque value is supplied with this listing. Ensure surfaces are clean and free of debris before assembly to achieve proper seating under the hex head.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/4-5 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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HCI81750400-001BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720316354866,"sku":"HCI81750400-001BX","price":70.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9bf7baf885d7b7542c6569d12ac10e4.jpg?v=1788562412","url":"https:\/\/voomisupply.com\/products\/value-collection-hci81750400-001bx-hex-head-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
