It features partial threading and a bright, uncoated finish, conforming to ASME B18.2.1 dimensional standards. Grade 8 steel provides high tensile strength, making this fastener appropriate for heavy-duty mechanical assemblies, structural connections, and industrial equipment applications. Installation requires a 1-1\/2 inch hex key or matching wrench. This screw is sold individually and is suited for use by millwrights, maintenance mechanics, and industrial assembly professionals.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in demanding mechanical and structural applications where high-strength fasteners are required. Partial threading allows for greater grip length in thicker assemblies and is commonly specified in heavy equipment, machinery frames, and industrial fixtures. The UNC thread standard ensures broad compatibility with standard inch-series tapped holes. The uncoated finish is appropriate for dry indoor environments or applications where a separate coating or plating will be applied after assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread size with partial threading for extended grip length\u003c\/li\u003e\n  \u003cli\u003e10-inch length under head accommodates thick structural assemblies\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with post-assembly coating processes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003eRequires 1-1\/2 inch hex wrench for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard inch-series tapped holes with 1-8 UNC thread form, suitable for heavy-duty mechanical and structural assemblies requiring Grade 8 fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified millwrights or mechanical assembly professionals familiar with high-strength fastener procedures. Always confirm the tapped hole thread form matches the 1-8 UNC specification before driving the screw. Use a calibrated torque wrench sized for the 1-1\/2 inch hex drive to achieve proper clamp load per the assembly specification. De-energize and lock out all equipment before replacing or installing fasteners in live mechanical systems.\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 10 inches\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\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\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\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: 2.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 451189BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697012638002,"sku":"451189BR","price":38.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9b4a5c5b33e3d5291e26f4db2bf268f.jpg?v=1788348462","url":"https:\/\/voomisupply.com\/products\/value-collection-451189br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
