INCLUDES: This Master SAE Detachable Cleanable Nut Driver Set includes 5 nut drivers in 1/4", 5/16”, 3/8”, 7/16”, and 1/2" sizes with removable socket ends that allow for easy cleaning, and two extension bars in 3-inch and 6-inch lengths. This set comes complete in a heavy-duty storage case with a slide lock. DESIGN: These nut drivers feature premium chrome vanadium steel construction with an industrial black manganese phosphate finish, offering superior durability and enhanced corrosion resistance. Each extension also includes a heavy-duty embedded magnet, ensuring fasteners stay secure in the socket during use, and a detent ball locking sockets securely to the extension. The included case makes organization and storage simple after the job is done. APPLICATION: These detachable / cleanable nut drivers offer greater ease of use than traditional nut drivers, which accumulate metal slag and debris over time and are difficult to clean, reducing magnetic function and increasing wear on the tool. The detachable socket ends allow for quick and easy cleaning, as well as quick swapping between socket sizes without removing the extension from the drill. With both a 3-inch and 6-inch extension, this set offers superior versatility for any job. RELIABLE | EFFECTIVE | EFFICIENT: Users trust ARES to be quality tools that make an impact.
