Tighten Fasteners with Torque Limiting Torque Screwdriver


The TLS is a preset torque screwdriver that's ideal for production applications where over-torque conditions are not tolerated. A preset torque screwdriver is similar to a person setting an alarm clock to signal the achievement of a selected time. The torque screwdriver is pre-set to the required torque value of the application and then the tool signals the operator when torque is achieved. A preset torque screwdriver does not feature an external adjustment scale. These tools have internal adjustment mechanism for setting the torque value and must be preset using a torque tester.

Preset screwdrivers are ideal for production applications where there is one torque setting required and you need to prevent incidental or operator tampering of the torque setting. However, if the torque specification changes or 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.

The cam-over philosophy of each Mountz hand torque screwdriver prevents a fastener or bolt from being under and over tightened. These torque tools ideal are for production applications where over-torque conditions are not tolerated. As a quality control tool, the torque screwdriver allows any user to deliver the correct torque with confidence regardless of task and operator skill level.

Mountz also offers the TLS torque screwdrivers in clean room configuration. The clean room screwdrivers are manufactured to comply with Class 100 Clean Room standards and are polished and sealed with a PTFE impregnated anodized coating that creates a tool nearly 40 times as clean as "off the shelf" torque tools.

Using a quality torque screwdriver makes a safer world through accuracy and precision. Controlling torque is essential for companies to ensure their product's quality, safety and reliability isn't compromised. The failure of a three-cent fastener that isn't properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently fastened can vibrate loose and excessive torque can strip threaded fasteners.
