It features a 5\/16-18 UNC thread and measures 2-1\/2 inches in length under the head. The screw is partially threaded and driven with a 1\/4-inch hex key. Constructed from alloy steel with a black oxide coating, it provides solid corrosion resistance in indoor and sheltered environments. This fastener is commonly installed by machinists, millwrights, pipefitters, and general mechanical contractors working on equipment assemblies, fixtures, and structural connections.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machinery assembly, equipment mounting, and structural fastening tasks across light industrial, commercial, and mechanical service environments. The 5\/16-18 UNC coarse thread pattern allows for quick engagement in through-holes and tapped bores. The partial threading is appropriate for applications requiring a smooth shank section, such as shoulder-style clamping joints or clearance-hole pass-throughs. This screw meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for engineered assemblies that require documented fastener grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for fast engagement in tapped steel and aluminum bores\u003c\/li\u003e\n  \u003cli\u003e2-1\/2-inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides a smooth shank section for shear-load and clearance-hole use cases\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers high tensile and yield strength per ASTM A574\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces surface corrosion and minimizes light reflection in field environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive compatible with standard hex keys and socket drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any tapped or through-hole application requiring a 5\/16-18 UNC thread and 2-1\/2-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/4-inch hex key or Allen-style socket driver.
