The two ends of the ring spanner are flower shaped, and the inner hole of the ring spanner is formed by two regular hexagons concentrically staggered by 30 degrees. Many ring spanners have elbows. The common angle of elbows is between 10 ° and 45 ° and the rotating bolt and handle are staggered from the side. The structure is convenient to dismantle the bolts and nuts assembled in the concave space, and can provide operation clearance for fingers to prevent scratches. For supplementary tightening and similar operations, a ring wrench can be used to apply large torque to the bolt or nut. There are various sizes of ring spanners. When using, choose the spanner corresponding to the size of bolt or nut. Because the wrench jaws are bihexagonal, the bolts / nuts can be easily assembled. This can be re installed in a limited space.
When using the box spanner, push the connection between the box spanner and the bolt with the left hand to keep the box spanner and the bolt fully matched to prevent slipping. Hold the other end of the box spanner with the right hand and apply force. The box spanner can encircle the head of the bolt and nut, so the bolt angle will not be damaged, and large torque can be applied.
When turning, it is strictly forbidden to put the extended pipe on the wrench to extend the length of the wrench to increase the torque, and it is strictly forbidden to hammer the wrench to increase the torque, otherwise the tool will be damaged. It is strictly forbidden to use the ring wrench with cracks and serious wear of the inner hole.
