Measuring 5\/16-24 thread size with a 3-inch length under head, this screw features partial threading and a zinc yellow dichromate finish that provides corrosion resistance in demanding environments. Manufactured to ASME B18.2.1 standards, it is appropriate for mechanical assemblies, equipment mounting, and structural connections where tensile strength and dimensional consistency are critical. Machinists, millwrights, maintenance technicians, and general contractors regularly specify Grade 8 hardware for high-load fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is suited for industrial, commercial, and heavy-duty mechanical applications where UNF fine-thread engagement is required. Fine-thread fasteners like the MP39337 are commonly used in applications where vibration resistance or precise torque control is important, such as machinery frames, automotive assemblies, and fabricated steel structures. The zinc yellow dichromate finish makes it appropriate for moderately corrosive service environments. This item is sold in packages of 25 units with a minimum order quantity of 1.\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\u003e5\/16-24 UNF fine-thread profile for improved vibration resistance\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading per ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish for moderate corrosion protection\u003c\/li\u003e\n  \u003cli\u003eHex drive head accepts standard hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 25 for shop and field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 5\/16-24 UNF tapped holes per ASME B18.2.1 specifications.
