Durofix RM601-34 Digital Torque Wrench Combo Kit Set, 3/8″ & 1/2″ Drive

Two calibrated wrenches, one kit – replace two tools with one purchase: 3/8-inch drive RM601-3S handles precision work from 5 to 50 Nm (brake calipers, spark plugs, bicycle stems) and 1/2-inch drive RM607-4 covers heavy fastening from 20 to 200 Nm (lug nuts, suspension, axle bolts). Each wrench is individually serialized and ships with its own ISO 6789 calibration certificate, hard-shell case, and user manual
High precision accuracy within plus or minus 2 percent: Clockwise accuracy within plus or minus 2 percent, counter-clockwise within plus or minus 3 percent across the full torque range – every unit is tested before shipment and ships with a traceable ISO 6789 calibration certificate. Resolution: 0.1 Nm, 0.1 ft-lb, 1 in-lb, and 1 kg-cm. Switch between four units of measure on the backlit LCD display for global jobs. This electronic torque wrench set meets the requirements of certified workshops and quality-control environments
Smart alert system with LED and buzzer notifications: As you approach the preset torque value, the LED flashes amber and the buzzer beeps faster; at target, the LED locks solid green and a continuous tone fires – no more guessing like a click-style wrench. Store up to six preset torque values and recall them with one button, suitable for repetitive fastening on assembly lines or service bays. This digital torque wrench with preset alert is built for professional automotive and heavy-duty use
Industrial-grade construction with ergonomic design: Industrial-grade chrome-vanadium ratchet heads with a 45-tooth fine-pitch reversible mechanism fit tight engine bays and narrow working spaces. Lightweight composite housing – 0.64 kg for the 3/8-inch and 1 kg for the 1/2-inch – with a textured soft-grip handle reduces vibration and hand fatigue on long shifts. Both wrenches operate on 4 AAA batteries (not included); auto power-off preserves battery life for automotive technicians, HVAC professionals, and fleet maintenance
Calibrated torque for the jobs that matter: wheel lug nuts (80 to 140 Nm), brake caliper bolts (25 to 45 Nm), spark plugs (15 to 35 Nm), motorcycle axle nuts (60 to 110 Nm), bicycle stem bolts (5 to 8 Nm), suspension control arms (90 to 160 Nm). This digital torque wrench set works for automotive, motorcycle, bicycle, and workshop applications. In the box: 2 digital torque wrenches (3/8-inch and 1/2-inch), 2 ISO 6789 calibration certificates, 2 hard-shell cases, 2 user manuals
