Partially threaded and conforming to ASME B18.2.1, this fastener is engineered for high-strength structural and mechanical assemblies. Grade 8 steel provides tensile strength suitable for demanding load-bearing applications. The zinc yellow dichromate coating offers corrosion resistance in both indoor and moderate outdoor environments. Thread size follows the Unified National Coarse (UNC) standard, ensuring broad compatibility with standard 1\/2-13 tapped holes and nuts. Length measurement is taken under the head at 3 inches. Sold in a package of 10.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in industrial, commercial, and mechanical assembly applications where high-clamping-force fasteners are required. Typical uses include equipment mounting, structural connections, machinery frames, and general fabrication work. The partial threading allows the unthreaded shank to act as a bearing surface in shear-loaded joints, making it a preferred choice for precision alignment and bolted connections subject to lateral loads. Suitable for use by millwrights, mechanical contractors, and maintenance technicians across a wide range of trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength in structural and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for shear-load bearing surface and precision alignment\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard (1\/2-13) for compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 10 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC nuts, washers, and tapped holes conforming to Unified National Coarse thread specifications per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by millwrights, mechanical contractors, or maintenance technicians using standard hex tooling.
