It features a 1\/4-28 UNF thread size with 1 inch of length under the head and is fully threaded along its entire shank. The 3\/16-inch hex drive socket head accepts a standard hex key or Allen wrench. Constructed from alloy steel with a black oxide finish, this screw delivers solid tensile strength and moderate corrosion resistance in controlled environments. It conforms to ASME\/ANSI B18.3 and ASTM A574 standards, making it a recognized fastener for precision and structural applications.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general mechanical assembly, jig and fixture work, machine component mounting, and other applications requiring a fine-thread socket cap fastener. The 1\/4-28 UNF thread pitch provides finer thread engagement than coarse-thread equivalents, making it well suited for thin materials, load-sensitive joints, or assemblies that require precise torque control. It is commonly used by machinists, millwrights, maintenance mechanics, and fabricators across industrial and light manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 UNF fine thread for precise thread engagement and controlled clamping force\u003c\/li\u003e\n\u003cli\u003eFully threaded shank provides maximum thread engagement throughout the 1-inch length under head\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive accepts standard Allen keys and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements for socket cap screws\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection in tooling applications\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-28 UNF hex socket cap screw per ASME\/ANSI B18.3, suitable for use in any application requiring a fine-thread alloy steel socket cap fastener of this size and drive type.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a 3\/16-inch hex key or Allen wrench. Ensure mating threads are clean and free of debris before installation. Apply thread-locking compound or specified preload torque per the assembly engineering requirements for the joint.
