TLS Preset Torque Screwdriver

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.

Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO 6789: 2003 (+/- 6% of setting).

How TLS Screwdriver is Preset & Operates

Various models that range from 0.7 ozf.in to 120 lbf.in.
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.
Bi-directional operation.
Four different colored lightweight aluminum handles allow color coding of specific torque values in production areas. (TLS1360 - Black only)

TLS - IFR Models (Impact Free Resetting)
The design action of the standard TLS cammed screwdrivers is such that when the tool reaches its pre-set torque value the mechanism disengages from the drive thus limiting the torque applied. Further rotation of the screwdriver handle resets the mechanism ready for the next torquing operation. The IFR models eliminates any small reaction during resetting. For more details.

TLS - OWC (One-Way Clutch with Locking Mechanism)
One-way clutch system is designed for the screwdriver to apply torque in one direction and lockup in the opposite direction for easy screw removal. Ideal for maintenance and refurbishing applications. For more details.
