Gedore DMSE 300 Tool Set Gedore 2641488 High Quality Durable

The Gedore DMSE 300 torque wrench (MPN 2641488) is an adjustable tubular torque wrench with a rectangular drive cavity designed for controlled screw tightening in the common range of 20–400 N·m (15–300 lbf·ft). Calibrated and supplied with a traceable test certificate, it is suitable for professional industrial and trade use where precise bidirectional torque application is required.

Advantages

This torque wrench is classified to DIN EN ISO 6789-2:2017 Type II Class A and calibrated to a maximum permissible deviation of ±3%, exceeding the ±4% required by the standard. It features a sturdy varnished tubular steel construction with a zinc-plated rectangular cavity (available in 9×12 mm or 14×18 mm), an ergonomic plastic handle with a calibration aid, a micrometre scale for fine N·m adjustments, and a release system that gives a tactile and audible signal when the set torque is reached. The tool offers change-over between N·m main scale and lbf·ft ancillary scale to reduce setting errors and has a secured adjusting/setting system with a reference symbol for torque adjustment.

Suitable for

• Controlled tightening of bolts and screws in industrial assembly
• Maintenance and repair work in automotive and mechanical workshops
• Applications requiring bidirectional torque control
• Tasks using sockets, reversible ratchets or open-end fittings with standardised depth gauges

Key specifications

• Torque range: 20–400 N·m / 15–300 lbf·ft
• Standard classification: DIN EN ISO 6789-2:2017 Type II Class A
• Calibration tolerance: ±3% (traceable test certificate included)
• Drive cavity sizes: 9×12 mm (factory depth gauge 17.5 mm) or 14×18 mm (factory depth gauge 25 mm)
• Construction: Varnished tubular steel with zinc-plated rectangular cavity and high-grade plastic parts

How to use

Set the required torque using the main N·m scale and, if needed, the micrometre scale for intermediate values. Use the N·m or lbf·ft scale as appropriate, switching scales to avoid reading errors. Fit end fittings with standardised depth gauges to ensure accuracy; operation with non-standard fittings can cause measurement inaccuracies. Apply torque in the required direction — the wrench is suitable for controlled bi-directional tightening. When the set torque is reached the release system will trigger a tactile and audible signal indicating the operation is complete.

Usage recommendations

For accurate results, always use end fittings with standardised depth gauges and follow the included traceable test certificate for calibration intervals. Depending on application and access, use front access (open-end fitting) or side access (reversible ratchet or socket).
