Wera T Metric Hex Key, Hex Size 4 mm, Overall Length 155mm, Non-Sparking, IEC 60900 Standard 05004981001

Wera 05004981001 T Metric Hex Key with a 4 mm hex size is a VDE-certified insulated tool crafted for precision screwdriving applications in industrial, mechanical, and fluid power sectors. It features a 155 mm overall length with a T-shaped handle that facilitates ergonomic and efficient power transfer, allowing operators to apply controlled torque for hexagon socket screws reliably.

The key is equipped with a robust slip clutch torque indicator, which provides a tactile and audible feedback signal once the preset tightening torque is reached, preventing over-tightening. Its non-sparking design makes it suitable for use in environments where spark generation poses hazards.

Compliance with IEC 60900 ensures that the tool has been individually tested for electrical safety up to 10,000 V, allowing safe working voltages of up to 1,000 V. The tamper-proof torque setting secures the specified torque value, avoiding accidental alterations during operation.

This tool is ideal for both tightening and loosening hexagon socket screws, with loosening torque values engineered to exceed the tightening torque, eliminating the need for additional tools during screw removal. The handle's softly rounded recessed grips allow comfortable use, decreasing hand fatigue during repetitive tasks.

Ergonomic T-handle for effective torque transfer and user comfort. Torque indicator with slip clutch prevents over-tightening and signals when torque is reached. Non-sparking and insulated for safety in sensitive and electrical environments.

IEC 60900 certified for electrical insulation up to 1,000 V. Robust design made in Czech Republic for industrial and mechanical precision. 4 mm hex size suitable for precision screwdriving applications. Tamper-proof torque setting ensures reliable and consistent torque application.

This professional-grade hex key is suitable for industrial manufacturing, mechanical maintenance, electrical assembly, fluid power systems, and laboratory equipment tasks requiring precise torque control. It effectively combines safety, ergonomic handling, and high-quality manufacturing standards, making it an essential tool for technicians and engineers.
