Screw Extractor Set Jonnesway AG010048 for Damaged/Broken Screws M3–M18, 5 pcs

Jonnesway AG010048 is a 5-piece screw extractor set designed to remove damaged, rounded or broken screws and bolts sized M3 to M18. The set covers a wide metric range and is intended for manual extraction using appropriate sockets, taps or adapters. Compact and organized, the extractors are suited to workshop, automotive and household repair tasks where fastener heads are stripped, rounded or snapped off.

Advantages

The set provides five different extractor sizes that together cover a continuous metric range from M3 to M18, enabling a single kit to handle small machine screws through larger bolts. Each extractor is designed for manual use with common hand tools, offering controlled torque application and reduced risk of further fastener damage. The compact grouping of pieces simplifies storage and selection during repair work.

Suitable for

• Removing stripped or rounded screw heads in mechanical repairs
• Extracting broken bolts from engines, gearboxes and machinery
• DIY household repairs where fasteners have corroded or sheared
• Workshop and maintenance tasks requiring metric-size extraction tools

Key specifications

• Number of pieces: 5
• Metric size coverage: M3–M18
• Intended use: manual screw and bolt extraction with sockets, taps or adapters
• Material: hardened steel for cutting and gripping (manufacturer specification)
• Suitable environments: automotive, industrial workshop, household maintenance

How to use

Select the extractor size that best matches the damaged fastener diameter. If necessary, drill a small pilot hole into the broken screw or bolt to provide a starting point. Insert the appropriate extractor into the pilot hole or onto the fastener and apply steady, controlled counter-clockwise torque using a compatible socket, tap wrench or adapter. Work slowly to avoid enlarging or further damaging the workpiece, and reverse direction if slippage occurs to re-seat the extractor.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Apply penetrating oil to seized or corroded fasteners before attempting extraction, and consider heating or additional loosening techniques for heavily corroded bolts. Match extractor size to fastener diameter and avoid excessive force to prevent tool breakage.
