It is partially threaded and supplied in a bright, uncoated finish. Manufactured to ASME B18.2.1 standards, this fastener is built for high-strength bolted joint applications where precise thread engagement and reliable clamping force are required. Machinists, millwrights, and maintenance technicians reach for Grade 8 hardware in demanding structural and mechanical assemblies where standard-grade fasteners are not sufficient.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy equipment assembly, industrial machinery, structural steel connections, and other high-load applications requiring fine-thread UNF fasteners in large diameters. The 1-3\/8-12 thread pitch makes it appropriate for assemblies where greater thread engagement and resistance to vibration loosening are priorities over coarse-thread alternatives. It is commonly used in manufacturing, fabrication shops, and field maintenance on heavy-duty mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-12 UNF thread provides finer pitch for improved vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for precise grip length in bolted joints\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for use where coating-free contact surfaces are required\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003e2-1\/16 inch hex key size for use with standard industrial wrenching tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension UNF hex head cap screw for use in any application requiring a 1-3\/8-12 thread, 6-inch-under-head length, Grade 8 fastener conforming to ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified machinists, millwrights, or maintenance technicians following applicable industry standards and equipment manufacturer guidelines. Always confirm mating thread class and material compatibility before installation. Use a properly sized 2-1\/16 inch wrench or socket to avoid fastener damage. Verify joint design, clamp load requirements, and any applicable torque specifications from the equipment OEM before final tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-3\/8-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: 2-1\/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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.21 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: 451715BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720324186418,"sku":"451715BR","price":27.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1205fcf81f266a39e5397f3afb882c_5b431217-820d-4638-9e6b-cf8e427536e0.jpg?v=1788562478","url":"https:\/\/voomisupply.com\/products\/value-collection-451715br-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
