Outil Wiha 320N Single

The Wiha 320N Single is an insulated slot screwdriver intended for work on and around electrical components up to 1,000 V AC. It has a 204 mm overall length and weighs 35 g, combining a hardened chrome-vanadium-molybdenum steel blade with a black finish and moulded insulation for safe use on live installations. The ergonomic SoftFinish® multi-component handle includes roll-off protection and a two-colour design for secure grip and easy identification.

Advantages

The blade is made of high-quality chrome-vanadium-molybdenum steel, through-hardened and finished in black for wear resistance. Insulation is moulded directly onto the blade to maintain electrical protection. The Wiha SoftFinish® handle offers ergonomic support and slip resistance, while roll-off protection improves safety when working at inclined surfaces or elevated positions. The tool is manufactured according to IEC 60900:2012 and meets DIN ISO 2380 standards.

How to use

Select the slotted screwdriver size that matches the screw head and ensure the tool is intact before use (no damaged insulation, cracks or wear). Hold the SoftFinish® handle firmly and apply steady torque while turning the screw. The moulded insulation allows work on or near live parts up to 1,000 V AC; however, use only in dry conditions and keep the handle and insulation clean to maintain protective properties. Store the tool away from solvents and extreme heat that could damage the insulation.

Recommendations

The Wiha 320N Single should be inspected regularly for insulation integrity. Do not use if insulation is damaged. Use appropriate personal protective equipment and follow local safety regulations when working on live electrical installations up to 1,000 V AC.
