Chrome vanadium steel, for screws with hexagon inserts, full insulated, 2-coloured coating-insulation - inside yellow / outside red.
Quality and Safety is most important in the Electrical Field. Therefore all HAUPA-VDE hand tools pass "individually" through a 10.000 volt waterbath in order to test the insulation-attribute. Our VDE-tools are subject to very strong test-prescriptions and have therefore the right to cover Safety-Signs.
The tests include for example:
- Pressure
- Flame resistance
- Adhesive strength of PVC coating
- Cold-heading
- Voltage
- Insulating properties
