Impact Free Torque Screwdrivers | TLS-IFR
The design action of the standard Impact Free Torque Screwdrivers TLS-IFR 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 this range of impact free torque screwdrivers handle resets the mechanism ready for the next torquing operation. The IFR models eliminates any small reaction during resetting.
Impact Free Benefits
- Various models that range from 1.2 – 120 lbf.in.
- All TLS-IFR models are “impact free” when the cam resets.
- Screwdriver is torque limiting in the CW direction only.
- Tamper-proof internal adjustment. No external adjustment scale – must be preset using a torque analyzer.
- Four different colored lightweight aluminum handles allow color coding of specific torque values in production areas. (TLS1360 – Black only)
The preferred and certified ranges of these tools is in accordance with the requirements of ISO 6789:2003 (+/- 6% of indicated setting).
Calibrating Torque Screwdrivers
To calibrate torque screwdrivers either use a torque tester or torque sensor within the range of the torque screwdriver. For
torque screwdrivers calibrate torque in “Peak” mode with a torque tester or torque sensor. Make sure to apply the torque
slowly and smoothly.
1. Select a torque tester or torque sensor that covers the torque range of the screwdriver.
Connect screwdriver to the torque tester or torque sensor using the appropriate adapters as
needed.
2. Apply torque clockwise slowly until screwdriver ‘slips’ and note reading.
3. Adjust screwdriver to required torque setting as described below.
4. Test and repeat adjustment as necessary to obtain desired value.
5. Recalibrate torque screwdriver at prescribed intervals.
