Long arms ensure excellent leverage, which makes driving easier. The ball ends of the keys allow them to be used up to an angle of 30 to the socket, whilst the hexagonal ends ensure an excellent fit into the screw/bolt head. Made of high quality steel, entirely hardened, with a phosphate finish, which provides protection against corrosion, providing a long lasting life. Each size is fitted with a different coloured injection moulding grip. Its soft-touch feeling is pleasant to hold, with non-slip grip and oil resistant. These different coloured grips also enable quicker identification of required size. Supplied in a compact sleeve-case for instant selection of the required size. It allows easy storage, whilst keeping the keys together. Specifications Sizes 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10mm. Piece 9.
