This screw features a 3\/8-16 UNC thread size, a 4-1\/2 inch length under head, and a 5\/16 inch hex drive. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and strength suited to industrial and mechanical assembly work. Partial threading along the shank provides positive clamping force between mating surfaces. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in general mechanical assembly, machine building, tooling fixtures, and structural fastening where a flush or low-profile socket head is required. The 3\/8-16 UNC coarse thread pattern is widely compatible with standard tapped holes in steel, aluminum, and cast components. It is commonly installed by millwrights, maintenance mechanics, and industrial assembly technicians in both shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length under head for deep-reach fastening applications\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch hex socket drive for use with standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves clamping force between joined components\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener for any application requiring a 3\/8-16 UNC hex socket cap screw with a 4-1\/2 inch length under head and partial threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 5\/16 inch hex key or socket driver.
