The combination spanner from Brüder Mannesmann in size 21 mm combines two types of wrenches in one tool: an open end on one side and a closed ring end on the other. Both ends have a 21 mm wrench size.

Material and Features

The flank protection system transfers force to the flats of the screw rather than the edges, preventing rounding, especially with seized connections. The ring completely encloses the screw head and transmits the highest torque, while the open end is used where a ring cannot be placed over the screw. The wrench is made of 6140 chrome vanadium steel according to DIN 3113.

Application Area

Ideal for automotive workshops, machine assembly, metal construction, and DIY enthusiasts. When loosening with the ring and quickly turning further with the open end, you work quickly and gently on materials with a single tool. This Green Line item comes with a 10-year warranty.
