TLS Preset Torque Screwdrivers
TLS is a preset torque limiting screwdriver (internally adjustable). The torque screwdriver is built with a cam-over design that prevents a fastener or bolt from being over-tightened. When the torque screwdriver reaches the preset torque value, the internal mechanism disengages from the drive, thus limiting the torque applied. Using a quality torque screwdriver ensures that proper torque is applied and maintains requirements associated with ISO quality standards.
