Bondhus, the world's leading Allen wrenches made in the USA. Top quality and performance. BLX 9 contains 9 hex wrenches in mm. Balldriver® hex - Save time-Bondhus® ball end wrenches are two tools in one. The ball end can be angled up to 30°. This makes it easier to access tight spaces and the shape of the hexagonal ball allows the tool to easily slide in and find its own grip on the screw. The end without the ball is used for tightening and loosening where a higher torque is needed. Twist-Lock holds the keys. The holder can be used as a handle.
