Hudy 5.0mm & 5.5mm Socket Driver
Hudy have released this very versatile and unique lightweight, compact duraluminum socket driver. The 5.0mm socket is the best tool for tightening/loosening M2.5 nuts from off-road shock pistons, while the 5.5mm socket is the best tool for tightening/loosening M3 nuts, such as those that secure off-road shocks to shock towers and more such as those used for mounting a touring car bodyshell rear wing.
