It is manufactured from Grade 8 steel with a bright, uncoated finish. The screw is partially threaded and conforms to ASME B18.2.1 dimensional standards. Weighing 2.08 pounds, this fastener is suited for high-strength bolted connections in structural, industrial, and heavy-duty mechanical assemblies. A licensed tradesperson or maintenance mechanic typically installs this fastener using a 1-11\/16 inch hex key or the corresponding wrench size.\u003c\/p\u003e\u003cp\u003eThis cap screw is used in applications requiring a high-strength inch-series fastener with a coarse UNC thread form. It is appropriate for structural steel connections, heavy equipment, and industrial machinery where Grade 8 tensile strength is specified. The partially threaded shank allows the unthreaded portion to bear shear loads without thread engagement in the grip zone, which is a common design requirement in mechanical and structural joints.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high clamping force and tensile strength\u003c\/li\u003e\n\u003cli\u003e1-1\/4-7 UNC coarse thread for reliable engagement in steel and heavy-duty applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank to distribute shear loads across the grip length\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for applications where coating is not required or specified\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n\u003cli\u003e1-11\/16 inch hex key size for standard wrenching\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application requiring a 1-1\/4-7 UNC Grade 8 partially threaded fastener meeting ASME B18.2.1 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson familiar with high-strength fastener torque requirements per applicable engineering specifications.
