Two sizes of ratchets and accessories give us a wide range of applications. The 1/2" size allows us to apply significant force. We can tackle stubborn screws not only with the ratchet itself, but also with a knob made from the adapter. The 1/4" size allows for use where nothing else will fit. Each size comes with a precision ratchet with 72 teeth (5° pitch), a set of hexagonal sockets, extensions and joints – that's the basics. What's worth paying special attention to in this set is: - spark plug sockets + joints + extensions + ratchets = the ability to unscrew spark plugs, even those deep in the engine block tilted backwards - the 1/4" screwdriver handle looks ordinary, but there's an additional 1/4" socket in the handle, which allows it to be used as an extension with an additional grip for precise guidance. If we add a set of bits with an adapter and a range of 1/4" sockets and a T-handle, practically anything can be unscrewed - the perfect complement are open-end wrenches, which, in addition to loosening and tightening screws, they are perfect as support when working with a ratchet to hold the screw or nut on the other side of the connection. - Socket wrenches - for quick loosening of screws without the need to remove the wrench from the screw and also as support when working with a ratchet The number of elements allows for thousands of combinations, and the possibilities are practically limited only by your imagination. All sockets, ratchets, and wrenches are made of high-strength chrome-vanadium steel (Cr-V). All screwdriver bits are made of S2 tool steel. All in a properly fitted, strong case with metal latches. **
