Park Tool Hex Wrench Set, Ball-End (4, 5, 6mm)
Park's AWS-8 Hex Wrench Set features Bondhus balldriver ends, which facilitate use when the tool is at an angle to the bolt. This is great for working in hard-to-reach areas, such as reaching water-bottle-cage screws. The AWS-8 has 4, 5, and 6mm wrenches, which are the most common bicycle bolt sizes. Plus, its Y shape and vinyl coating provide excellent leverage and comfort.
Park's Bondhus balldriver ends fit into bolts straight on and from an angle, which makes it easy to access bolts in hard-to-reach places.
