Designed to suit production torque requirements in high volume manufacturing. Accuracy ±5%, repeatable, guarantees equal tightness every time. Lightweight construction provides less fatigue for the operator and encourages use. Wrenches slip when predetermined torque setting is reached, thus completely eliminating overtightening. Automatic reset signalled by audible click. All models have corrosion resistant stainless steel head and moulded non slip hand grip.
TSN25D has 36 teeth ratchet. TSN55 and TSN125 have 48 teeth ratchet. Setting the required torque is easily done using either static or electronic instruments.
