It is partially threaded and left bright with no finish coating. Grade 8 steel provides high tensile strength for heavy-duty fastening in structural, mechanical, and industrial assemblies. This fastener conforms to ASME B18.2.1 dimensional standards. It is driven with a 1-11\/16-inch hex key and is sold individually. Machinists, millwrights, maintenance technicians, and construction tradespeople install this type of fastener in high-load bolted joint applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy equipment, structural steel connections, industrial machinery, and other applications requiring a high-strength inch-series UNF fastener. The partial threading allows the unthreaded shank to bear shear loads in close-tolerance bolt holes, making it appropriate for precision assemblies and rigid connections where full-thread fasteners are not specified. Its bright uncoated finish is typical for dry or interior service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel for high tensile and proof load capacity in demanding applications\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-12 UNF thread provides fine-pitch engagement for precise clamping force control\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank handles shear loads in close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fitment\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to account for in torque calculations\u003c\/li\u003e\n  \u003cli\u003e1-11\/16-inch hex key drive size for standard industrial tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNF hex head cap screw for use in any application specifying a 1-1\/8-12 x 4-inch Grade 8 fastener per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 1-11\/16-inch hex wrench or socket. Follow the torque specifications called out in the applicable engineering drawing or equipment service manual — no generic torque value applies to all Grade 8 joints. Inspect mating threads for cleanliness and damage before assembly. Reuse of high-strength fasteners in critical structural joints should follow the original equipment manufacturer guidance or applicable structural codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 inches\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 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\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.47 pounds\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: 451017BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51719341605170,"sku":"451017BR","price":32.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8341f00e6903ab3573d9cdc8011a031c.jpg?v=1788558913","url":"https:\/\/voomisupply.com\/products\/value-collection-451017br-hex-cap-screw-1-1-8-12-x-4-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
