Long-Lasting Use: WORKPRO Swivel Socket Set is constructed from drop-forged and heat-treated chrome-molybdenum steel for extreme durability and strength for impact operations, and corrosion-resistant black manganese phosphate finish, providing durability for manual use
Easily Identify the Adapter You Need: This set includes 1/2, 1/4, and 3/8 inch drive universal joints, high contrast laser-etched size markings, which can be identified clearly even in weak light, and convenient for you to choose
Flexible Access to Hard-to-Reach Fasteners: The socket adapter features a ball spring design that distributes the torque load over a larger surface area, and can be rotated 360 degrees to perfectly adapt to any angle, allowing flexible access to fasteners even in tight spaces and awkward angles
Secure Connection and Locking: The concave four-corner interface can be firmly connected to the drive tool, the pinhole helps to lock on the drive end handle, and the spring-loaded detent ball can firmly connect the socket to prevent it from falling off
Wide Range of Uses: The universal joints can be used with all pneumatic, electric and manual tools, suitable for maintenance of cars, trucks, motorcycles and bicycles, mechanical repair and wrench socket transformation
