It features a 82-degree flat head driven by a 3\/8-inch hex socket, making it suitable for use with standard Allen keys or hex socket drive tools. The fastener is manufactured from alloy steel with a black oxide finish, which provides moderate corrosion resistance and reduces light reflection in finished assemblies. The screw measures 4.5 inches in overall length with a 5\/8-11 UNC thread form and is partially threaded. It meets ASME\/ANSI B18.3 and ASTM F835 standards. Licensed mechanics, millwrights, and general maintenance technicians are the primary installers of this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is used in machinery, tooling fixtures, structural assemblies, and industrial equipment where a low-profile or flush-mount fastener is required. The 5\/8-11 UNC thread size is a coarse-thread designation common in heavy industrial and mechanical applications. The black oxide alloy steel construction suits indoor and controlled-environment installations. Partial threading is standard for longer grip-length applications where clamping force must be distributed across an unthreaded shank section.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush or countersunk installations\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive compatible with standard Allen and socket drive tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM F835 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion resistance and low reflectivity\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for improved clamping in thick-material assemblies\u003c\/li\u003e\n  \u003cli\u003eUNC 5\/8-11 thread standard per ASME\/ANSI B18.3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC replacement or new-install flat socket cap screw for machinery, fixtures, and industrial assemblies requiring a 5\/8-11 coarse-thread, 82-degree countersunk fastener in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or mechanical technicians using a 3\/8-inch hex socket driver or Allen key.
