Torque screwdrivers

Torque screwdriver

— screwdrivers of this type have a mechanism built into the handle that allows you to limit the force with which the tip acts on the fastener when turning. The specific limit is set by the user. As long as the force on the tip is below the specified value, the tool works like a regular screwdriver, but as soon as this value is exceeded, the handle begins to turn relative to the tip (usually with a characteristic sound), and the tip has almost no effect on the fastener. Such features are indispensable for delicate work, when it is important not to “tighten” the connection.
