These come with Grip-it handle which provides sturdy grip to maximize torque. 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. Tool sizes are molded into the handle for easy to select size. Blades are high torque and rotate independently up to 270°.
