The Bahco 9-piece Hexagon Key Set is ideal for driving bolts and screws that have hexagonal sockets. Long arms ensure excellent leverage, which makes driving easier. The ball ends of the keys allow the keys to be used up to an angle of 30 degrees to the socket, whilst the hexagonal ends ensure an excellent fit into the screw/bolt head. The keys are black oxidised and are therefore resistant to corrosion. The set is supplied in a compact sleeve-case for instant selection of the required size. It allows easy storage, whilst keeping the keys together. Consists of the following offset metric keys: Sizes: 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm and 10mm.
