We offer Allen Key, which is an L-shaped tool having a rod with hexagonal cross section. It is used to drive screws and bolts with the help of hexagonal sockets in its head. It requires a key of different sizes for each screw size that helps in inserting the screw into its hole. The Allen Key is generally used to assemble furniture and repair vehicles. Also, it is light in weight, hence can easily get into the hard-to-reach places on a vehicle, especially two-wheelers. That is why cyclists prefer to carry it with them while riding.
