The 50mm and 100mm extensions provide additional reach, with a T-piece to make a T-handle if necessary. The T-piece also pulls double duty as a 1/4 inch to 3/8 inch drive adapter. The driver bits and accessories are nickel plated to fight corrosion. Completing the set is a 1/4 inch square drive screwdriver handle and set of 1.25, 1.5, 2, 2.5 and 3mm Allen keys. Packed in a powder coated steel box, each piece stays put in a molded plastic tray.
