Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets ASME B18.2.1 dimensional standards. The UNF (Unified National Fine) thread form and Grade 8 material rating make it suited for high-strength bolted connections where precise clamping loads are critical. It weighs 1.89 pounds. Tradespeople and industrial maintenance technicians use this screw where structural and mechanical joint integrity is required.\u003c\/p\u003e\u003cp\u003eThis cap screw is appropriate for heavy equipment assemblies, structural steel fabrication, machinery mounting, and industrial maintenance applications requiring a fine-thread, high-strength fastener. The partial threading allows the unthreaded shank to bear shear loads across a joint, a configuration commonly specified in machine design and structural bolting. A 1-11\/16-inch hex key or wrench is required for installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high-strength bolted joint applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank suited for shear-load and close-tolerance fits\u003c\/li\u003e\n\u003cli\u003eUNF thread standard (1-1\/8-12) for finer thread engagement and higher clamp load than coarse thread equivalent\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup to affect thread fit or torque values\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n\u003cli\u003e1-11\/16-inch hex drive for standard wrench compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME B18.2.1 inch-series hex head cap screw suitable for any application specifying a 1-1\/8-12 UNF Grade 8 partially threaded fastener with 5.5 inches of length under the head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical, structural, or maintenance tradespeople familiar with high-strength fastener torque procedures. Always verify hole diameter and thread class before installation to ensure proper fit. Use a calibrated torque wrench and follow applicable industry or equipment manufacturer torque specifications for Grade 8 fasteners of this diameter. De-energize, depressurize, or otherwise render safe any equipment before servicing fastened joints.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\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: 1.89 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 451020BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692567265586,"sku":"451020BR","price":18.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5345ca74930fea4c0b95be7daf02b6f4.jpg?v=1788299436","url":"https:\/\/voomisupply.com\/products\/value-collection-451020br-hex-cap-screw-1-1-8-12-x-5-1-2-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
