Knipex Schraubzange

Multi-ring wrench for metric and imperial screws and nuts with widths from 10 to 32 mm (3/8 to 1¼ inches). Self-locking from 17 mm: no slipping off the workpiece. Play-free and slip-free gripping of metric or imperial hex screws to prevent rounding of screw heads. Reliable and firm grip on round, rusty, or thick-coated screws and bolts. Quick tightening of bolted connections with ratchet mechanism. Press the button to adjust to the workpiece, also possible with just one hand. Fine adjustment for optimal fitting to different workpiece sizes and a comfortable grip width. Box joint design for high stability through double guidance. Reliable capture of the hinge pin: no unintentional shifting. Favorable leverage for optimal power transmission. The pinch protection prevents the operator's fingers from getting caught. Replaces a set of wrenches, ideal for tightening lock nuts.
