Flat Impact Screwdriver Topex 8x250 mm model 39D255 (MPN 4165)

Flat Impact Screwdriver Topex 8x250 mm model 39D255 is a hand tool designed for loosening and tightening slotted (flat-head) screws by converting a hammer strike into controlled torque. The tool has an 8 mm blade width and a 250 mm shaft that allows access to recessed or hard-to-reach fasteners in maintenance, carpentry and mechanical applications. Its impact mechanism reduces slipping and helps apply higher torque than a standard screwdriver while maintaining user control.

Advantages

The flat impact screwdriver combines a hardened impact blade with a sturdy shaft to resist deformation under percussive loads. Its longer 250 mm reach improves access to deep-set screws, and the impact design helps prevent cam-out when applying high torque. The handle and shaft are built to withstand repeated hammer strikes, making the tool suitable for demanding service and repair tasks where percussive tightening or loosening is required.

Suitable for

• Automotive and mechanical repair where slotted screws are tight or corroded
• Carpentry and joinery work requiring access to recessed fasteners
• Maintenance and service tasks in workshops and industrial environments
• Situations where controlled impact torque is needed to free or set fasteners

Key specifications

• Blade type: flat (slotted) blade
• Blade width: 8 mm
• Shaft length: 250 mm
• Impact mechanism: percussive torque transmission for hammer strikes
• Intended use: manual impact loosening and tightening of slotted screws

How to use

Position the 8 mm flat blade into the slotted head of the screw, ensuring a snug fit to minimize slipping. Hold the screwdriver firmly with the shaft aligned to the screw axis and apply a controlled hammer strike to the butt end to transmit torque through the impact mechanism. Use successive controlled blows rather than excessive force to avoid damaging the screw head. For tightening, rotate the tool to the desired torque between strikes, checking the screw seating periodically.

Usage recommendations

Use eye protection and gloves when performing impact operations. Inspect the blade for wear or rounding before use and replace the tool if the blade is damaged. Select the flat impact screwdriver for slotted screws that require percussive torque; for other screw head types, use the matching impact tool to avoid damage.
