Bahco 74WR-100 Click-Type momentsleutel met doorgaande vierkantaandrijving, 1/2 inch, 20-100 Nm

Precise torque application is critical for safety and reliability in mechanical assembly, yet many wrenches lack the accuracy and convenience needed for consistent results. The Bahco 74WR-100 click-type torque wrench solves this by delivering a controlled, audible and tactile signal when the preset torque is reached, preventing over- or under-tightening. Its through-square drive design allows the square to be pushed through the head, enabling clockwise and counterclockwise torque application without turning the wrench over.

Who is it for

Professional mechanics, technicians, and demanding DIYers who need a reliable, accurate torque wrench for automotive, industrial, and maintenance tasks. It is ideal for applications requiring torque values between 20 and 100 Nm, such as wheel nuts, engine components, and flange bolts.
