7430 ESD Kraftform adjustable torque screwdriver 0.10-0.34 Nm with Rapidaptor chuck - Wera 05074780001

Small screws on electronic assemblies need a precisely controlled tightening torque and protection against electrostatic discharge. The Wera 7430 ESD covers 0.10 to 0.34 Nm (10 to 34 Ncm) with a scale graduation of 0.015 Nm and gives a distinctly audible and noticeable release when the set torque is reached. A surface resistance of ≤ 10^9 Ohm dissipates charges in a controlled way.

Benefits

• Torque set by hand without special tools, easy-to-read scale.
• Supplied magnifier clips onto the scale for better readability.
• Accuracy ± 6 % as per DIN EN ISO 6789, clear release signal at the set value.
• Unlimited torque for loosening seized screws.
• Rapidaptor quick-release chuck for rapid change of 1/4" bits.
• Multi-component Kraftform handle with hard and soft zones, hexagonal anti-roll feature.

Applications

Assembly and service on circuit boards, connectors, sensors and precision mechanics in ESD protected areas, wherever very low torque values must be repeated reliably.

Standards and safety

The resistance requirements for ESD screwdriving tools are taken from DIN EN 61340-5-1, which includes a handle made of a defined electrically conductive material. Accuracy complies with DIN EN ISO 6789.
