Flat-head screwdriver Topex 3x100 mm 1000V insulated, model 39D471

Topex flat-head screwdriver model 39D471 has a 3 x 100 mm blade and insulation rated to 1000 V for work on live circuits within the specified voltage limit. The tool combines a hardened steel blade with an ergonomically shaped insulated handle to provide precise torque transfer when turning slotted screws in electrical and general maintenance applications. The blade width and length match common flat-head fasteners while the 1000 V insulation reduces risk during tasks on powered installations when used according to safety standards.

Advantages

The Topex 3x100 mm 1000V insulated flat-head screwdriver provides electrical insulation certified for work up to 1000 V, a durable steel blade finished for wear resistance, and a handle shaped to improve grip and control. Its blade geometry is matched to standard slotted screws to reduce cam-out, and the insulated handle and shaft provide continuous protection along the tool’s working length. The compact 100 mm blade length makes the screwdriver convenient for use in confined spaces and for routine maintenance where precise control is required.

Suitable for

• Turning standard slotted (flat-head) screws in electrical installations
• Maintenance and repair work on live circuits up to 1000 V (when used with proper precautions)
• Assembly and disassembly of household and industrial equipment with slotted fasteners
• Use by electricians, installers, and maintenance technicians

Key specifications

• Blade: flat (slotted) profile, 3 mm width
• Blade length: 100 mm
• Insulation rating: 1000 V
• Handle: insulated, ergonomic shape for improved grip
• Material: hardened steel blade with protective finish

How to use

Verify the screwdriver’s insulation integrity before use and ensure the tool is clean and free from damage. Select the flat-head screwdriver size that fits the screw slot to minimize slipping. Position the blade fully into the screw slot, apply steady axial force, and turn with controlled torque. When working on live circuits, confirm that the tool’s 1000 V rating is appropriate for the system voltage and follow applicable electrical safety procedures, including using personal protective equipment and observing safe work distances.

Usage recommendations

Inspect the insulated handle and blade regularly for cracks, wear or damage; do not use the screwdriver if the insulation is compromised. Clean the tool after use and store it separately from uninsulated tools to avoid damage to the insulating layer. For work on circuits near or above the insulation rating, de-energize the circuit or use tools with a higher rated insulation.
