It is manufactured from alloy steel and finished with a zinc yellow dichromate coating that provides corrosion resistance and a distinctive yellow appearance for easy identification. The shank is partially threaded, making it suited for applications that require a grip length or bearing surface between clamped components. This fastener meets ASME B18.2.1 dimensional standards and is installed by millwrights, maintenance technicians, and mechanical contractors in structural and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in heavy-duty mechanical and structural applications where Grade 8 tensile strength is required. Typical uses include machinery mounting, heavy equipment assembly, jig and fixture fabrication, and general industrial maintenance. The partially threaded configuration is particularly useful in bolted joints where shank engagement through a clearance hole is needed before threading into a tapped hole or nut. It is sold in multiples of 10.\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\u003e3\/4-10 UNC thread form with partial threading for grip-length applications\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head for deep-reach or stacked-component assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and visual identification\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional consistency and interchangeability\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; length measured under the head\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or new-installation fastener for any application requiring a 3\/4-10 UNC Grade 8 hex head cap screw per ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified maintenance technicians or mechanical contractors using a standard 1-1\/8-inch hex wrench or impact driver with the appropriate socket. Always ensure mating threads are clean and free of debris before assembly.
