Chiave dinamometrica GEDORE DREMASTER 2641240 con cricchetto 1/2" (12,5 mm) 40-200 Nm

Over-tightened bolts can strip threads or snap, while under-tightened ones may vibrate loose—both can cause equipment failure, safety hazards, or costly rework. The GEDORE DREMASTER 2641240 torque wrench removes the guesswork from critical fastening, delivering precise, repeatable torque from 40 to 200 Nm so every fastener is tightened to specification with confidence.

Who is it for

Built for professional mechanics, maintenance technicians, and serious DIY enthusiasts who demand reliable torque accuracy. It is ideal for wheel nuts, cylinder head bolts, and other critical fasteners on cars, trucks, and industrial machinery. If you work in a workshop, service center, or production environment where torque compliance is mandatory, this wrench is an essential addition to your toolkit.

Tips

Always store the torque wrench at its lowest setting to maintain calibration accuracy. Avoid using it as a breaker bar or for loosening fasteners, as this can damage the mechanism. For consistent results, apply torque in a smooth, steady pull until you hear and feel the click, then stop immediately.
