TLS Preset Torque Screwdrivers

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