It is manufactured from Grade 8 alloy steel, which provides high tensile strength and resistance to shear loads. The fastener carries a zinc yellow dichromate finish that offers corrosion resistance in demanding service conditions. With a 1-8 UNC thread form and an 8-inch length under head, this screw is suited for thick structural assemblies where a full-thread fastener would be inadequate. Installation is performed with a standard hex wrench or impact driver sized to the 1-1\/2 inch hex drive. Machinists, millwrights, and field mechanics commonly specify this grade and configuration.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy structural bolting, machinery assembly, and equipment fabrication where Grade 8 strength is required. The partial thread allows for shank engagement through clearance holes before threading into the receiving member, making it appropriate for bolted joint assemblies with a nut or tapped blind hole. It is commonly found in industrial plant maintenance, agricultural equipment repair, and general mechanical construction. The 1-8 UNC thread is a coarse-pitch standard widely used in North American fastener applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for corrosion protection\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC coarse-thread form per ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head with partial thread for shank clearance applications\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch hex drive compatible with standard wrenches and impact tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for structural and mechanical assemblies requiring a 1-8 UNC partially threaded hex head cap screw with Grade 8 alloy steel specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanics or millwrights following applicable torque specifications for Grade 8 fasteners as defined by the joint design engineer or equipment manufacturer. Always de-energize and lock out equipment before fastener replacement or assembly work. Use the correct 1-1\/2 inch hex wrench or impact socket to avoid rounding the drive head.
