400 i VDE Hex insulated torque-indicator, hexagon socket 4 mm, 5.0 Nm - Wera 05004980001

Tightening hexagon socket screws to a defined torque on live installations calls for an insulated tool that releases reliably. The 400 i VDE Hex for 4 mm is fixed at 5.0 Nm and individually tested at 10,000 V for work up to 1,000 V.

Benefits

• Error-free screwdriving thanks to a slip clutch that cannot be overtightened and exact torque transmission.
• Distinctly audible and noticeable excess-load signal when the pre-set torque is reached.
• Tamper-proof against changing of the set torque value.
• Loosening torque significantly higher than the tightening torque, so no additional tool is usually needed to loosen.
• Ergonomic T-handle marked with screw symbol, size, torque and maximum release torque.
• Hex-Plus profile with larger contact surfaces protects the screw head and fits every standard hexagon socket screw.

Applications

Assembly and maintenance in switchgear, distribution boards and power supply, wherever 4 mm hexagon socket screws close to live parts must be tightened repeatably to 5.0 Nm.

Standards and safety

Individually tested at 10,000 V as per IEC 60900 for safe working at the approved voltage of 1,000 V.
