Series 4000

Click Torque Wrenches 3°

Classic torque wrench with non-graduated adjustable setting. When the set value is reached, the wrench clicks and for about 3° it does not apply any tightening torque.

The standard 9×12 and 14×18 drives allow these wrench to use both reversible ratchets and accessories of different types, for example with open-end or ring inserts.
(See Accessories section).

The adjustable version with graduated scale is also available (see 4000SR series).
