Screw Extractor Set Jonnesway AG010104 for Broken Screws M3–M25 8 pcs

Jonnesway screw extractor set AG010104 includes eight hardened extractors sized to remove broken or severely stripped screws and bolts from M3 up to M25. Designed for workshop and repair environments, the set provides a step-efficient method to recover damaged fasteners when the head or thread is compromised and conventional tools cannot gain purchase. The extractors are made for use with hand drills, tap wrenches or extractor sockets to back out remaining fastener shanks without enlarging the hole or damaging surrounding material.

Advantages

The extractors are heat-treated for strength and shaped to bite into damaged screw cores for reliable engagement. Covering a range from small M3 fasteners to larger M25 bolts, the eight-piece set reduces the need to carry multiple individual tools. Their spiral flute geometry converts rotational force into secure grip, enabling controlled removal of broken screws and minimizing further thread damage. The compact set is suitable for mobile toolkits and fixed workshops alike.

Suitable for

• Automotive repair and maintenance
• Machinery servicing and industrial equipment repair
• Metalworking and fabrication where thread rescue is needed
• General workshop tasks involving stripped or broken screws and bolts

Key specifications

• Number of pieces: 8
• Applicable fastener sizes: M3–M25
• Material: hardened steel (heat-treated)
• Flute type: spiral/left-hand to improve bite into damaged cores
• Compatibility: usable with hand drills, tap wrenches, extractor sockets
• Finish: corrosion-resistant surface treatment

How to use

Select the extractor size that closely matches the diameter of the broken fastener. Center-drill a small pilot hole into the remaining shank if required to provide a starting point. Fit the extractor into a suitable driver—such as an extractor socket or tap wrench—and apply slow counterclockwise rotation so the spiral flute digs into the screw core. Maintain steady, controlled torque to back the fragment out; use light tapping if necessary to seat the extractor before turning. For seized or heavily corroded fasteners, apply penetrating lubricant and allow time to work before attempting extraction.

Usage recommendations

Use appropriate personal protective equipment and secure the workpiece before attempting extraction. If excessive torque is needed, reassess the pilot hole alignment and extractor engagement; avoid applying sudden high-impact forces that may fracture the extractor or the component. For critical or hardened fasteners, consider professional assistance to prevent damage to mating parts.
