Measuring 1-8 thread size with a 9-inch length under head, this fastener features partial threading and conforms to ASME B18.2.1 dimensional standards. The bright, uncoated finish leaves the steel surface bare, making it suitable for applications where a specific coating will be applied after installation or where coating is not required. This screw is sized for installation with a 1\/2-inch hex key or wrench and follows the Unified National Coarse (UNC) thread standard.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in applications requiring a high-strength fastener capable of handling significant clamping loads. Grade 8 classification makes it appropriate for heavy equipment assembly, machinery frames, structural connections, and similar demanding mechanical installations. The partial threading is suited for through-bolt applications where an unthreaded shank provides a bearing surface in the grip area. Machinists, millwrights, maintenance technicians, and mechanical contractors are the primary installers of fasteners in this class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof strength requirements\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread form for compatibility with standard coarse-thread nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a solid bearing surface in the grip zone\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional consistency and interchangeability\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for secondary coating or bare-steel applications\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex key size for installation with standard hex wrenches or sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC coarse-thread hex head cap screw conforming to ASME B18.2.1, suitable for use with Grade 8-rated nuts and hardware in inch-measurement fastener assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of Grade 8 hex head cap screws should be performed by a qualified mechanic or maintenance technician using calibrated torque equipment to achieve the required clamping load for the joint specification. De-energize and lock out all equipment before performing fastener work on live machinery. Apply thread lubricant or anti-seize only when specified by the joint design, as dry torque values differ from lubricated values. Verify that mating threads and bearing surfaces are clean and free of debris before assembly.\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: 9 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\/2 inch\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: 2.2 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: 451187BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716398416178,"sku":"451187BR","price":38.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_f3697d55-7fe8-4728-80e9-887de22ae71f.jpg?v=1788525432","url":"https:\/\/voomisupply.com\/products\/value-collection-451187br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
