RS PRO Triple Pack 33 Piece Hex Key Set

From RS PRO, this triple pack of hex key sets are a portable way to be prepared for any hex driving eventuality. With two packs of long-armed L-shaped keys in plastic holders, and a folding pen-knife style hex set, a variety of sizes are available.

The plastic cases keep your hex keys neat and organized, with handy size guides imprinted for ease of selection. The pen-knife style hex key has a gorilla grip which is stronger than steel, and is ideal for precision applications.

The ball end ensures you can insert the key into a hex socket at different angles, which is handy for when sockets are in awkward or obstructed locations. Also, the long arm L-wrenches are ideal for deep-set bolts.

This 33-piece key set is corrosion resistant and is made from chrome vanadium steel, for a long and dependable tool life.

Often referred to as an allen key, the hex key is a driver designed for hex nuts and sockets, and are generally easier to turn and apply torque than more conventional screws. As such, they are ideal for when fasteners need to be adjusted or equipment needs to be dismantled.

The t-handle means that the hex keys can be used with less operating space, and the ball end allows non-straight insertion into sockets. As such, this set is better suited than conventional l-shaped hex keys for precision work.

From furniture assembly to bicycle maintenance, this hex key set is ideal.
