This fully threaded fastener features a 4-48 UNF thread and a 7\/16 inch length under head. The 3\/32 inch hex drive accepts a standard hex key for controlled torque application. Constructed from alloy steel with a black oxide finish, this screw provides solid mechanical strength and corrosion resistance appropriate for indoor mechanical and industrial assemblies. It is a small-diameter, fine-pitch fastener suited for applications where standard coarse-thread screws are not appropriate.\u003c\/p\u003e\u003cp\u003eThis socket cap screw is used in precision mechanical assemblies where fine-thread engagement and a low-profile head are required. Typical applications include instrument enclosures, light machinery, fixture fabrication, and tooling jigs. The 4-48 UNF thread pitch is common in small mechanical and instrument-grade assemblies. Licensed machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-48 UNF fine thread for precise, high-engagement fastening\u003c\/li\u003e\n\u003cli\u003eFully threaded along the full 7\/16 inch length under head\u003c\/li\u003e\n\u003cli\u003e3\/32 inch hex socket drive compatible with standard hex keys\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides surface protection and reduces light reflection in optical or instrument applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-fit fastener for assemblies requiring a 4-48 UNF hex socket cap screw with a 7\/16 inch length under head and 3\/32 inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a calibrated 3\/32 inch hex key or hex bit driver.
