It features a 1\/2-13 UNC thread size with a 3-inch length under the head and is partially threaded, allowing for secure clamping in through-bolt and blind-hole applications. Manufactured from alloy steel with a zinc-plated finish, this fastener delivers solid corrosion resistance and mechanical durability. It is driven with a 3\/8-inch hex (Allen) key, making it compatible with standard socket tools found in most trade shops and fabrication environments. This screw meets ASME B18.8 and ASTM A574 standards.\u003c\/p\u003e\n\u003cp\u003eThis hex socket cap screw is suited for use in industrial machinery, general fabrication, maintenance and repair operations (MRO), and structural assemblies where a recessed-drive, high-strength fastener is required. The partial threading is appropriate for applications where a smooth shank section is needed for precise hole location or bearing load distribution. Machinists, millwrights, maintenance technicians, and fabricators commonly use this fastener type in both production and field service settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form for broad compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partial threading for shank-bearing load applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex drive for use with standard Allen wrenches and hex bit sockets\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in general indoor and light-duty outdoor environments\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 replacement or new-installation hex socket cap screw for any application requiring a 1\/2-13 UNC partially threaded fastener with a 3-inch length under head and 3\/8-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, fabricators, or maintenance technicians using a 3\/8-inch hex key or socket driver.
