Founded from a German tool forge in 1919, Gedore Tools has built a solid reputation over these many years. Because of this, you’ll know you can rely on Gedore’s series of slogging spanners for the tough jobs they’ll need to do. Slogging spanners are designed to be hit with a hammer to tighten fasteners just a little bit more. Each of the wrenches in this series are offset by 15-degrees to give you a bit more power than you would otherwise.
