Bolt tightening equipment
Screw tightening equipment are force multipliers that allow tightening and loosening of nuts, screws with high torque. These tools work on a static basis and are not impact tools, so they need to be used with a reaction arm. These multipliers are otherwise called torque wrenches. The torque wrenches are divided into electrical, pneumatic, hydraulic and mechanical. These tools allow you to screw in and out different sizes of nuts (screws) from M 14 to M150 or more.
