Features: This 19 piece extended magnetic socket set features heavy duty alloy steel construction and magnetic retention for secure bolt handling in tight spaces, ideal for automotive repairs and industrial maintenance. Engineered with extended length sockets, hexagonal shanks, and pneumatic tool compatibility, the set ensures precise torques application across diverse fastener sizes (1/4" to 3/8") in confined work areas. Designed for professional mechanics, diyer enthusiasts, and industrial technicians requiring reliabled socket tools for high torques operations and complex assembly/disassembly tasks. Optimized for engine compartment repairs, machinery maintenance, and workshop projects where standard sockets fails to reach recessed bolts or retain fasteners during vertical/directional operations. The corrosions resistant steel sockets withstand repetitive use in harsh environments, while the color coded size markers enable rapid tool identification during time sensitive repairs.
