Flat Screwdriver Topex 4.0 x 100 mm 39D802 — flat-head screwdriver 4.0mm tip, 100mm blade

Flat-head screwdriver Topex 4.0 x 100 mm (model 39D802) is a hand tool designed for driving and removing slotted screws. The tool features a 4.0 mm flat tip and a 100 mm blade length that provide a precise fit for standard slotted heads. The straight blade construction ensures stable contact with the screw slot, while the handle shape supports controlled hand-driven torque and accurate alignment during maintenance, electrical work and general assembly tasks.

Advantages

The screwdriver combines a narrow 4.0 mm tip with a 100 mm shaft to reach recessed screws and fit slim slotted heads. The straight blade offers rigidity for consistent force transfer and minimal tip wobble. The ergonomically shaped handle improves grip and control for manual turning, reducing slippage and enabling more precise adjustments. The tool's simple, durable design suits repeated use in workshop and field conditions.

Suitable for

• General maintenance and repair of household devices
• Electrical installation and small electrical repairs (where insulated tools are not required)
• Furniture assembly and disassembly involving slotted screws
• Precision mechanical adjustments and hobby work

Key specifications

• Tip type: flat (slotted)
• Tip width: 4.0 mm
• Blade length: 100 mm
• Blade shape: straight shaft for stable engagement
• Handle: hand-shaped for torque and control
• Intended use: manual hand-driven operation

How to use

Select the flat screwdriver when the screw head matches a 4.0 mm slotted tip. Insert the tip squarely into the screw slot to ensure full contact along the blade width. Apply steady, controlled turning force with the handle while keeping the blade aligned with the screw axis to avoid cam-out and damage to the screw head. Use the 100 mm blade length to reach screws set slightly below the work surface or recessed in narrow spaces.

Usage recommendations

Do not use the screwdriver on live electrical circuits unless the tool is specifically rated and insulated for electrical work. Inspect the tip for wear before use; replace the tool if the tip is rounded or damaged to maintain proper fit and reduce the risk of slipping. For high-torque applications consider using a screwdriver with a larger tip or a power tool designed for that purpose.
