It carries a Grade 8 steel rating, which indicates a tensile strength suitable for demanding load-bearing connections. The fastener measures 1-8 thread size with a 9-1\/2 inch length under head, and features partial threading along the shank. The uncoated bright finish is standard for applications where plating is not required or where the installer will apply their own protective treatment. Installation uses a 1\/2 inch hex key drive. This screw conforms to ASME B18.2.1 and uses UNC thread standards.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in heavy equipment, structural steel connections, machinery frames, and industrial fabrication where Grade 8 tensile performance is specified. The partially threaded shank provides a bearing surface that resists shear loads, making it suitable for bolted joints where precise clamping and alignment are critical. Mechanical contractors, millwrights, ironworkers, and maintenance technicians 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 strength in load-bearing joints\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides shear resistance and accurate joint alignment\u003c\/li\u003e\n  \u003cli\u003eUNC thread form per ASME B18.2.1 standard ensures dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for dry environments or secondary coating\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch hex key size for standard socket and wrench tooling\u003c\/li\u003e\n  \u003cli\u003e9-1\/2 inch length under head accommodates thick structural members\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC Grade 8 hex head cap screw for use in inch-series bolted assemblies requiring ASME B18.2.1 conformance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or trades professional familiar with structural fastening requirements. Always degrease mating threads and apply thread lubricant or anti-seize as specified by the joint design before torquing. Use a calibrated torque wrench and follow the torque specification from the equipment manufacturer or applicable engineering standard. Do not reuse fasteners that show signs of yielding, thread damage, or corrosion.\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: 9-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\/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\u003eWeight\u003c\/strong\u003e: 2.3 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: 451188BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694794277170,"sku":"451188BR","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_de0dcf99-aaaf-4095-868c-af2c48ca5b2a.jpg?v=1788328463","url":"https:\/\/voomisupply.com\/products\/value-collection-451188br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
