TWM Range

The TWM range of industrial manual torque wrenches offers 7 models with torque capacities from 7 to 630 lbf.ft (10 to 850 Nm) having square drive sizes from 3/ 8” to 3/4”. All models are designed and manufactured to meet or exceed the highest demands of industry and are marked with a unique serial number and supplied with a calibration certificate.

The TWM manual torque wrenches have a dual scale reading both Nm and lbf.ft and are ideally suited for applications requiring repeatable, accurate torqueing of bolts and nuts. The push-through square drive and integrated ratchet head allows the wrench to be used for controlled bi-directional torqueing. All models incorporate an ergonomic handgrip and integrated locking mechanism to prevent accidental alteration of the torque setting during operation. The click system is activated immediately once the required torque is achieved.
