Description
All Klein hex wrenches feature precision chamfered hex ends. Precision chamfering eliminates cut off burr problems. The cut off burr found on other common hex keys often exceeds the allowed clearance between the screw and the key, interfering with socket engagement. Balldriver keys have a patented ball design that allows for a thicker neck diameter increasing torque capacity while maintaining operational angles to 25%.
