It features a 1\/2-20 UNF thread size with a 3-inch length under head and is partially threaded. The 3\/8-inch hex drive accepts a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide finish, this screw provides good tensile strength and moderate corrosion resistance in dry or lightly oiled environments. It meets ASME\/ANSI B18.3 and ASTM A574 standards, which specify dimensional and mechanical property requirements for socket cap screws used in demanding applications.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for use in machine tool components, jigs, dies, hydraulic manifolds, and general industrial assemblies where a recessed-drive, high-strength cap screw is required. The 1\/2-20 UNF fine thread pitch is preferred in applications requiring precise torque control or where vibration resistance is important. This screw is appropriate for use by machinists, millwrights, maintenance technicians, and mechanical contractors working with steel or iron components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-20 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n\u003cli\u003e3-inch length under head with partial threading for clamping grip in thicker assemblies\u003c\/li\u003e\n\u003cli\u003e3\/8-inch internal hex drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides a low-reflectance surface and light corrosion resistance in dry or oiled service\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 ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 1\/2-20 UNF partially threaded fastener with a 3\/8-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8-inch hex key or Allen driver of appropriate quality for the torque demands of the joint.
