It features an 82-degree flat head driven by a 5\/8-inch hex socket, and is manufactured from alloy steel with a black oxide finish for corrosion resistance in moderate environments. The screw measures 1-8 thread size by 8 inches in overall length and is partially threaded. It conforms to ASME\/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and maintenance technicians install this fastener in structural assemblies, machinery, and fabricated components where a low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for use in general industrial, mechanical, and structural applications where UNC threading and a countersunk seating angle of 82 degrees are specified. The black oxide finish offers mild corrosion resistance and reduces light reflection, making it appropriate for both interior mechanical assemblies and light-duty outdoor applications. The partial threading allows for clamping force in joints where thread engagement is needed only at the receiving member, a common requirement in thicker material stacks.\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\u003e5\/8-inch hex socket drive for reliable torque application with standard hex keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for clamping force in thick-material assemblies\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and general-purpose replacement or specification fastener for assemblies requiring a 1-8 UNC flat socket cap screw with an 8-inch overall length and 82-degree head angle, per ASME\/ANSI B18.3 and ASTM F835.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 5\/8-inch hex key or socket driver. Ensure the mating countersink is machined to the correct 82-degree angle before installation to achieve full head seating. De-energize and lockout any equipment before fastener replacement or removal.
