It features a 1\/4-28 UNF thread, a 3\/16-inch hex drive socket, and a 2-inch length under head. The screw is partially threaded and manufactured from alloy steel with a black oxide coating for corrosion resistance. It meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a reliable choice for applications requiring precise thread engagement and repeatable clamping force. Installation requires a standard 3\/16-inch hex key or hex driver.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for use in industrial machinery, tooling fixtures, hydraulic assemblies, and general mechanical fabrication where a flush or recessed fastener head is required. The 1\/4-28 UNF fine thread pitch provides higher thread strength and finer adjustment compared to coarse thread equivalents, making it appropriate for applications with metal-to-metal contact or thin-wall components. Trade machinists, millwrights, and maintenance technicians commonly use this screw type in both original equipment and field repair work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 UNF fine thread for higher tensile strength and finer clamping control\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive for use with standard hex keys or L-wrenches\u003c\/li\u003e\n\u003cli\u003e2-inch length under head with partial threading for unthreaded grip section engagement\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and IFI 124 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension hex socket cap screw per ASME\/ANSI B18.3, suitable for any application requiring a 1\/4-28 UNF partially threaded socket head cap screw with a 2-inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/16-inch hex key or hex bit driver. Ensure mating threads are clean and free of debris before assembly. De-energize and lock out any equipment before replacing or installing fasteners in live machinery.
