HAZET 6144-1CT Chave dinamométrica 3/4 polegadas 200-500 Nm

This professional 3/4 inch drive torque wrench delivers precise, controlled tightening from 100 to 600 Nm. Its short-path release mechanism provides a clearly audible and tactile signal when the set torque is reached, preventing over-tightening and ensuring repeatable accuracy in demanding industrial applications.

Advantages

Calibrated to ±2% of scale value in the direction of actuation, this tool meets DIN EN ISO 6789-2:2017 and comes with a test certificate. The reversible ratchet head with 32 teeth allows work in tight spaces, while the ergonomic 2-component handle reduces operator fatigue. A safety locking mechanism prevents accidental adjustment, and the clearly legible scale with 5 Nm divisions enables fast, precise setting.
