It is manufactured from Grade 5 steel with a zinc-plated finish that provides corrosion resistance in standard service environments. The screw follows the Unified National Coarse (UNC) thread standard with a 1-8 thread size and measures 4.5 inches under the head. Machinists, maintenance technicians, and trade professionals install this fastener where a high-strength, coarse-thread bolt with a partially unthreaded shank is required for proper load distribution or shear strength.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is suited for structural and mechanical assemblies in residential and commercial construction, HVAC equipment mounting, plumbing support structures, electrical panel installations, and general equipment fabrication. The partial threading leaves a smooth shank section that resists shear loads and allows the fastener to act as a locating pin in close-tolerance applications. It is sold in packages of 16 units, making it practical for single-trade jobs or small-batch repairs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction delivers medium-to-high tensile strength suitable for structural fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion resistance for indoor and sheltered outdoor use\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank reduces shear stress at the joint interface\u003c\/li\u003e\n  \u003cli\u003eUNC 1-8 thread standard ensures broad compatibility with standard hex nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e4.5-inch length under head accommodates thicker material stacks and deep-clearance assemblies\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 16 supports single-job use without excess inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC hex head cap screw compatible with any 1-8 threaded hex nut, coupler, or tapped hole conforming to Unified National Coarse thread specifications in the inch measurement system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or trade technicians using a standard hex wrench or socket set sized for a 1-inch nominal bolt head. Torque the fastener to values appropriate for Grade 5 hardware per ASME or applicable industry standards for the joint material and lubrication condition. Do not substitute a coarse-thread nut on this fastener without confirming 1-8 UNC compatibility. Ensure mating threads are clean and free of debris before installation to avoid galling the zinc finish.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Partially Threaded\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 16\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: -30170-41\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695060615474,"sku":"-30170-41\/2","price":128.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02706050c2dfc0ae15cef1c13ce7309c.jpg?v=1788330942","url":"https:\/\/voomisupply.com\/products\/value-collection-30170-41-2-hex-cap-screw-1-8x4-5in-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
