The Brüder Mannesmann ring spanner, size 18 x 19 mm, completely encloses the bolt head, thereby transmitting the highest torque of all spanner types. The flank protection system protects the edges of the bolt.

Material and Features

Because the ring encloses the bolt all around, the force is distributed evenly, and the spanner does not slip, even when you apply significant force. The flank protection system additionally transfers force to the surfaces rather than the edges. The spanner is made of 6140 chrome vanadium steel according to DIN 838, which specifies hardness, torque, and dimensional accuracy. As a double ring spanner, it covers two sizes: 18 x 19 mm.

Area of Application

Ideal for car workshops, machine assembly, metal construction, and DIY enthusiasts dealing with seized screw connections that require high force. This Green Line item comes with a 10-year warranty.
