This fully threaded cap screw features a 5\/8-18 UNF thread size, a 1-1\/2 inch length under head, and a 1\/2 inch hex drive. Constructed from alloy steel with a zinc-plated finish, it delivers the hardness and corrosion resistance needed in demanding mechanical, industrial, and structural assembly work. Installation requires a standard 1\/2 inch hex key or allen driver. This screw meets ASME B18.8 and ASTM A574 standards, confirming it is rated for high-strength fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in general mechanical assemblies, machine frames, tooling fixtures, and industrial equipment. The fine 18-TPI thread pitch on the 5\/8 inch diameter shank provides improved thread engagement and resistance to loosening under vibration, making it a common choice in automotive, manufacturing, and maintenance applications. The zinc-plated coating adds a layer of corrosion protection appropriate for indoor and light-duty service environments. It is typically installed by machinists, millwrights, and maintenance technicians working with close-tolerance assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for improved vibration resistance and precise clamping force\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 1-1\/2 inch under-head length for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch internal hex drive for high-torque socket wrench or allen key installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated to ASTM A574 high-strength fastener specification\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for general indoor service use\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8 dimensional standards for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.8 and ASTM A574 compliant hex socket cap screw suitable for general mechanical and industrial assemblies using 5\/8-18 UNF threaded bores.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/2 inch hex key or socket driver; ensure the mating threaded bore is clean and free of debris before driving. Power down or de-energize any equipment before performing fastener service on mechanical assemblies. Apply thread lubricant or thread-locking compound as required by the assembly specification.
