The Bahco BE-9770 is a professional 9-piece metric hex key set designed for driving bolts and screws with hexagonal sockets. This L-shaped allen key set features long arms that deliver excellent leverage, making it easier to apply the necessary torque when working with stubborn fixings across a range of mechanical and assembly tasks. The ball end design is a key feature that enables the keys to be used at angles up to 30° to the socket, particularly useful when access is restricted or when working in tight spaces. The hexagonal ends ensure an excellent fit into screw and bolt heads, minimising the risk of rounding and providing reliable grip under load. Each key benefits from a phosphate finish surface treatment that delivers outstanding protection against corrosion whilst improving accuracy at the tip. The set is supplied in a compact sleeve-case that allows instant size selection and keeps all keys organised together, ideal for mobile tradespeople and workshop storage alike. The comprehensive size range from 1.5mm through to 10mm covers the most common metric hex socket requirements encountered by mechanics, engineers, and assembly professionals.
