The Wiha T-handle hex screwdriver 27930 is a VDE-insulated tool designed for working with metric allen (hex) screws. The chrome-vanadium steel blade is through-hardened with a black finish and the insulation is moulded directly onto the blade. The T-handle is VDE-insulated and the tool is individually tested for protective insulation up to 1,000 V AC and manufactured according to IEC 60900:2012.

Advantages

Individually tested for protective insulation to 1,000 V AC and VDE and GS tested, the screwdriver provides electrical safety for live work. The through-hardened chrome-vanadium blade offers strength and wear resistance while the black finish reduces glare. The insulation moulded onto the blade and the VDE-insulated T-handle ensure consistent electrical protection. Compact weight (84 g) and an ergonomic T-handle provide controlled torque for precise fastening.

How to use

Select the appropriate metric hex size and insert the blade into the allen screw head so it seats squarely. Grip the insulated T-handle and apply steady torque to tighten or loosen the screw, keeping hands on the insulated surfaces while working near live circuits. After use, inspect the insulation for damage and store the screwdriver in a dry, protected place.

Recommendations

Use only if the tool’s insulation and markings are intact. Do not use a damaged or modified screwdriver for live electrical work. Follow applicable safety rules for working on or near energized equipment and replace the tool if insulation is compromised.
