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.

• Precision radial ball clutch slips-free when the preset torque is reached preventing over-torquing
• Thrust bearings insure that the torque setting is independent of any end load applied by the operator
• Tamper-proof internal adjustment. No external adjustment scale - must be preset using a torque analyzer
• Provide bi-directional operation and are calibrated in either the CW or CCW direction

When the torque screwdriver reaches the pre-set torque value the internal mechanism disengages from the drive thus limiting the torque applied.
