It features a 5\/16-18 UNC thread size and measures 2.75 inches in length under the head. Drive engagement is through a 1\/4-inch internal hex socket, compatible with standard hex keys and socket drivers. The screw is manufactured from 4037 alloy steel and finished with a yellow cadmium plating, which provides corrosion resistance and a visual inspection indicator. This fastener meets ASME B18.3 dimensional standards, making it a reliable choice for precision mechanical assemblies, MRO applications, and industrial maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in mechanical, industrial, and maintenance environments where a partially threaded socket head fastener is required. The 5\/16-18 UNC coarse thread pattern offers strong clamping force and resistance to loosening under vibration. The yellow cadmium finish is commonly specified in aerospace, defense, and heavy equipment applications where corrosion protection and traceability are important. Licensed trades and industrial maintenance professionals install this type of fastener in machine components, brackets, and structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for strong clamping and vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows precise shear and load distribution\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n  \u003cli\u003e4037 alloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eYellow cadmium plating provides corrosion resistance and finish identification\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 fastener dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw suitable for applications requiring a 5\/16-18 UNC partially threaded fastener with a 1\/4-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated torque wrench and a 1\/4-inch hex key or socket bit to avoid fastener damage. Ensure mating threads are clean and free of debris before installation.
