The Wera 5004595001 3 Piece 12 Sq. Wheel Impaktor C Set from ITS are designed for use with electric or pneumatic impact wrenches due to their robust Impaktor technology. The rotating plastic sleeve allows for higher control during screwdriving. In addition, the surface of the rim is protected. The plastic sleeves are interchangeable. The internal plastic insert protects the surfaces of the wheel bolts. The hexagon profile allows the transmission of high forces and puts less strain on the edges of bolts or screw heads than a double hexagon profile. Fine-toothed ratchets also make the use of a double hexagon profile superfluous, even in confined spaces, thanks to their small return angle. The Take it easy tool finder system - with profile and size colour-coding for quick and easy tool selection. Colour-coded system for hexagon drive screws L-Keys, Zyklop bit sockets, external hex drive screws and nuts Joker wrenches, Zyklop sockets and Zyklop bit sockets with holding function, and TORX drive screws L-Keys, Zyklop bit sockets.
