l = Gauge dimension of extended insert tool holder
Formula: Torque correction factor for change in effective length
HAZET torque wrenches are adjusted/calibrated with the „l2 insert dimensions“.
If other insert tools are used, then the formula must be observed.

Torque screwdrivers

Fine feeling – for the smallest of torque values

• Application with standard F bits (e.g. HAZET 2204 to 2225)
as well as by using the 2304 adapter with 6 sockets
• Torque ranges: 0.1 – 6 Nm
• Accuracy (of scale value) ± 5% (6002 CT and 6003 CT) or ±6 – 15% for 6001 series
