TLS (Torque Limiting Screwdrivers Internally Adjustable)
TLS (Torque Limiting Screwdrivers Internally Adjustable)

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

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.

Bi-directional operation.

Four different colored lightweight aluminum handles allow color coding of specific torque values in production areas. (TLS1360 - Black only)

ESD compliant IEC 61340-5-1:1998

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.

What’s a preset tool? How do you set the torque on the TLS screwdriver? See video.
