Sized at 5\/16-18 UNC with 1 inch of length under the head, this fastener is fully threaded and driven by a 1\/4 inch hex key. Constructed from alloy steel with a black oxide finish coating, it provides solid corrosion resistance in moderate-exposure environments. It meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for applications requiring documented fastener compliance. Electricians, pipefitters, and general contractors reach for this screw when securing panels, brackets, and structural assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in a wide range of industrial and mechanical assemblies where a low-profile, high-torque socket drive fastener is required. The 5\/16-18 UNC coarse thread provides reliable engagement in steel and aluminum tapped holes. The black oxide finish suits indoor and light-duty outdoor installations where moderate corrosion protection is acceptable. It is appropriate for machine assembly, equipment mounting, and panel fabrication work across HVAC, electrical, plumbing, and general mechanical trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for reliable engagement in tapped steel and aluminum\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 1 inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex drive compatible with standard hex keys and socket sets\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion resistance and reduces light glare\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3, ASTM A574, and IFI 124 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex socket cap screw suitable for use in any tapped hole or application requiring ASME\/ANSI B18.3 and ASTM A574 compliant fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/4 inch hex key or matching socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Do not over-torque alloy steel cap screws in soft base materials such as aluminum without referencing applicable torque specifications for the assembly.
