Screw extractor set Topex 14A110 for broken screws, sizes M3.3–M19, 5 pieces

The Topex screw extractor set 14A110 is a five-piece kit designed for removing broken, seized or damaged screws and bolts in metric thread sizes from M3.3 to M19. Each extractor has a stepped reverse-profile that bites into the remaining shank when turned counterclockwise, enabling controlled removal of fasteners without damaging surrounding material. The set is compatible with standard drill chucks and common hand rework tools, making it suitable for workshop repairs, automotive maintenance and general metalworking tasks.

Advantages

The set includes five extractors covering a wide range of metric thread sizes, reducing the need to purchase multiple individual tools. Stepped extractor profiles provide improved grip on damaged fasteners while minimizing further deterioration of the screw or bolt. Compatibility with standard drill chucks and manual tools ensures flexible use in different repair environments. The compact five-piece design makes storage and transport straightforward for mechanics and technicians.

Suitable for

• Removal of broken or seized screws and bolts in workshops
• Automotive maintenance and repairs
• General metalworking and machinery servicing
• Home repair and do-it-yourself projects involving damaged fasteners

Key specifications

• Number of pieces: 5
• Thread size coverage: M3.3 to M19
• Extractor type: stepped reverse-profile extractors
• Compatibility: standard drill chucks and common hand rework tools

How to use

Select the extractor that corresponds to the diameter of the remaining shank or the thread size range. Drill a pilot hole into the broken fastener if required, mount the extractor in a drill chuck or appropriate hand tool, insert the extractor into the pilot hole and turn counterclockwise with steady pressure so the stepped profile can bite into the fastener. Continue turning until the fastener backs out. If resistance is high, apply penetrating lubricant and allow time to work before retrying. Use appropriate protective equipment and secure the workpiece to prevent movement during extraction.

Usage recommendations

For best results, inspect the damaged fastener to choose the correct extractor size and create a clean pilot hole. Begin with low-speed turning to avoid additional damage and increase torque gradually. When working on threaded assemblies, protect surrounding threads and surfaces, and consider thread repair options if the original thread is compromised after extraction.
