Chave dinamométrica GEDORE DREMASTER 2641240 com catraca 1/2 polegadas (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.
