Tool set Gedore DMK 200

The Gedore DMK 200 is an adjustable, releasing tubular torque wrench with integrated ratchet and square drive for industry and trades. It provides controlled screw tightening in the common torque range of 20–850 N·m (15–630 lbf·ft) and is suitable as a guide for screws from M7‑10.9 to M24‑8.8 and M30‑5.6. The tool is supplied with traceable calibration and meets the DIN EN ISO 6789‑2:2017 Type II Class A standard, calibrated to a maximum permissible deviation of ±3%.

Advantages

The Gedore DMK 200 offers bidirectional controlled tightening and a sturdy, varnished tubular steel construction with a zinc‑plated ratchet head and high‑quality plastic components. The ergonomic plastic grip includes a calibration aid and an adjustment system with a reference symbol for precise setting. A micrometre scale on the N·m main scale allows setting of interim torque values, and the scale can be switched between N·m and lbf·ft to avoid reading errors. The release mechanism provides a tactile and audible signal when the set torque is reached.

Suitable for

• Industrial assembly and maintenance requiring precise torque control
• Automotive and commercial vehicle repair where specific torque values are required
• Mechanical and technical workshops working with fasteners M7 to M30

Key specifications

• Model: Gedore DMK 200 (MPN: 2641240, EAN: 4002805931387)
• Torque range: 20–850 N·m / 15–630 lbf·ft
• Accuracy: calibrated to ±3% (DIN EN ISO 6789‑2:2017 Type II Class A), traceable test certificate included
• Drive: square drive with integrated ratchet (DMK series features 1/2" mushroom head interchangeable square; from DMK 400 models 3/4" push‑through square)
• Construction: varnished tubular steel, zinc‑plated ratchet head, premium plastic parts
• Features: bidirectional tightening, micrometre scale for interim N·m values, switchable N·m / lbf·ft scale, tactile and audible release signal

How to use

Set the desired torque using the main N·m scale and the micrometre scale for interim values; switch to the lbf·ft ancillary scale if required. Lock the setting with the secured adjusting system and, if needed, perform rapid setting using a hexagon Allen key (not included). Apply the square drive to the fastener and operate the ratchet in the required direction for controlled tightening. The release mechanism will trigger a tactile and audible signal when the preset torque is reached; then stop applying force to avoid over‑torquing.

Usage recommendations

Use the Gedore DMK 200 within its specified torque range and have the tool recalibrated at regular intervals according to workplace or manufacturer requirements to maintain accuracy. Store the wrench at its lowest scale setting and protect it from impacts and corrosive environments to preserve calibration and mechanical integrity.
