Brand: Beta Tools
The 935 Series tubular wrenches from Beta Tools feature a 6-point socket at each end. The body is hollow so you can reach a nut at the base of a long stud. Holes in the body allow the use of a "tommy" bar cross handle for leverage. A hex profile on the outside of each end also let you use a standard open-end or adjustable wrench. Each wrench fits two different size fasteners for maximum coverage.
This set consists of the 8 smallest metric wrenches in the 935 Series:
6x7, 8x9, 10x11, 12x13, 14x15, 16x17, 18x19, 20x22
In addition, the two matching tommy bars 940/1 and 940/2 are included.
