Manufactured from Grade 8 steel with a bright uncoated finish, this screw delivers exceptional tensile strength suitable for demanding bolted connections. The fastener measures 1-1\/4-12 thread size with a 9-inch length under the head and features partial threading along the shank. It conforms to ASME B18.2.1 standards, making it a reliable choice for precision-fit applications where dimensional consistency is required. Licensed tradespeople and maintenance professionals working with heavy equipment, machinery mounts, or structural steel will find this fastener appropriate for their applications.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is suited for use in industrial maintenance, equipment assembly, and structural bolting scenarios where high clamping force and shear resistance are required. The UNF thread standard and partial threading make it appropriate for applications where a strong unthreaded shank section is needed to resist lateral loads or provide a precision fit through clearance holes. It is commonly installed by millwrights, pipefitters, and maintenance mechanics working on heavy machinery and structural frames.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartial threading along the shank allows the unthreaded section to bear shear loads and fit precisely through clearance holes\u003c\/li\u003e\n  \u003cli\u003eUNF 1-1\/4-12 thread specification ensures fine-thread engagement for secure clamping in high-vibration environments\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use in dry indoor environments or where post-installation coatings will be applied\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fitment and interchangeability\u003c\/li\u003e\n  \u003cli\u003e1-7\/8-inch hex key size compatible with standard industrial wrenches and impact tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fastener for industrial bolted assemblies requiring a 1-1\/4-12 UNF, Grade 8, partially threaded hex head cap screw per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician using a properly sized 1-7\/8-inch wrench or impact socket. Always de-energize and lock out equipment before replacing or installing fasteners in mechanical assemblies. Follow applicable torque specifications from the equipment manufacturer or relevant structural codes — do not estimate torque values without a reference specification. Use a calibrated torque wrench for critical joints to ensure proper clamp load without overloading the fastener.\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\/4-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 9 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: 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: 1-7\/8 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: 3.62 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 451052BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711545016626,"sku":"451052BR","price":25.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa6534786a032b3bf63d4ee14877b621.jpg?v=1788476797","url":"https:\/\/voomisupply.com\/products\/value-collection-451052br-hex-cap-screw-1-1-4-12-x-9-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
