The ring spanner from Brüder Mannesmann in the size 12 x 13 mm completely encloses the screw head, thereby transmitting the highest torque of all spanner types. The flank protection system protects the edges of the screw.
Material and Features
Because the ring encloses the screw all around, the force is distributed evenly and the spanner does not slip, even when you apply force. The flank protection system also transmits the force to the surfaces instead of the edges. The spanner is made of chrome vanadium steel 6140 according to DIN 838, which defines hardness, torque and dimensional accuracy. As a double ring spanner, it covers two sizes with 12 x 13 mm.
Application Area
Ideal for car workshops, machine assembly, metal construction and DIY enthusiasts for seized screw connections that require high forces. You receive a 10-year warranty on this Green Line item.
