KNIPEX on Instagram: "The knurled nut won't turn? The KNIPEX Cobra® 87 01 250 can help! Thanks to 25-step fine adjustment at the touch of a button, you can quickly adjust the pliers to workpieces up to Ø 50 mm. The jaw geometry ensures that the Cobra® clamps itself onto the workpiece. This self-clamping effect, combined with the with non-slip handles, allows for an almost loss-free transfer of the applied torque. This way, every machine maintenance job is a breeze😊🔧 #knipex #knipexcobra #tools
