Designed for fastening applications where errors simply aren't acceptable, the FG-40i preset torque screwdriver applies the right amount of torque every time. Preset hand torque screwdrivers are ideal for fastening applications where operators repeatedly assemble parts at the same torque setting. Built with a cam-over design, the accurate screwdriver prevents a fastener or bolt from being under and over-tightened. As a quality control tool, the screwdriver allows any user to deliver the correct torque with confidence regardless of task and operator skill level. Using a quality torque screwdriver ensures that proper torque is being applied and maintains requirements associated with ISO quality standards. 

The torque screwdriver is pre-set to the required torque value of the application. A preset torque screwdriver does not feature an external adjustment scale. These tools have an internal adjustment mechanism for setting the torque value and must be preset internally using a hex key and a torque tester. However, if the torque specification changes or a new project requires a different torque setting, the preset torque screwdriver is still flexible enough that a new torque setting can be set internally using a torque analyzer.
