TLS-IFR
PRESET TORQUE SCREWDRIVERS

The error-proofing torque screwdriver is engineered with a cam-over mechanism that prevents over-torque. These screwdrivers are fitted with an IFR (Impact Free Resetting) cam that eliminates any slight reaction occurring during the screwdriver’s resetting, which is ideal for assembling shock-sensitive components. Preset hand torque screwdrivers are suitable for fastening applications where operators repeatedly assemble parts at the same torque setting. As a quality control tool, the screwdriver allows any user to deliver the correct torque with confidence regardless of task and operator skill level. Using a quality torque screwdriver ensures that proper torque is being applied and maintains requirements associated with ISO quality standards.

The preferred and certified ranges of these tools is in accordance with the requirements of ISO 6789 (+/- 6% of indicated setting).

TOOL BENEFITS

  • Preset torque limiting screwdriver (internally adjustable).
  • 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 torque analyzer.
  • Precision radial ball clutch “slips-free” when the preset torque is reached preventing over-torquing.
