short description:

Bondhus® brand ball-ended wrenches. 12 piece set with rubber holder, sizes from .05" to 5/16".

more information and instructions:

These come with a manufacturer's lifetime warranty and are extremely tough. Sizes include: .05, 1/16, 5/64, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, and 5/16. A proprietary coating prevents water from penetrating the surface.

The ball end allow the wrench to turn at an angle as the picture shows, which can be very helpful in tight spots. It also makes insertion of the tool into the screw head much faster.
