Bolt Extractor Set 5 pcs M3-M18

The Bolt Extractor Set 5 pcs M3-M18 is a precision tool collection designed for professionals and serious hobbyists who need to remove damaged or seized fasteners without damaging the surrounding material. Each set contains five specially engineered extractor bits that cover a wide range of metric sizes from M3 up to M18, ensuring versatility across automotive, aerospace, machinery, and construction applications.

Key Features

• High‑Strength Construction: All extractor bits are forged from chrome‑vanadium steel with a hardness of 54 HRC. This material choice guarantees exceptional durability, resistance to wear, and the ability to withstand high torque without bending or breaking.
• Precision Machining: Each bit is ground to exact tolerances, providing a perfect fit for its corresponding bolt size. The sharp cutting edges allow clean extraction even from heavily corroded or over‑tapped fasteners.
• Ergonomic Design: The extractor heads feature a comfortable grip and are sized to fit standard drill or screwdriver bits, enabling quick tool changes without the need for additional adapters.
• Clear Plastic Packaging: The set is housed in a durable clear plastic box that protects the tools during transport and storage. The transparent design allows instant visual inspection of each extractor’s condition.
• Wide Size Range: With sizes M3, M4, M5, M6, M8, M10, M12, M14, and M18, this set covers the most common metric fasteners used in industrial and automotive repair.

Applications

The extractor set is ideal for:

• Automotive Repair: Removing broken wheel studs, suspension bolts, or engine mounting screws.
• Aerospace Maintenance: Extracting damaged fasteners from aircraft components where precision and reliability are critical.
• Industrial Machinery: Replacing seized bolts in heavy equipment, conveyor systems, or manufacturing lines.
• Construction Projects: Removing corroded nails or screws from structural steel or timber framing.
• DIY and Hobbyist Work: Fixing broken fasteners on bicycles, motorcycles, or custom builds.

How to Use the Set Effectively

1. Select the Correct Size: Identify the bolt’s nominal diameter and choose the corresponding extractor bit. Using a mismatched size can damage both the fastener and the tool.
2. Align Properly: Position the extractor tip against the damaged head, ensuring it sits flush with the surrounding material to avoid slippage.
3. Apply Gradual Torque: Turn the drill or screwdriver slowly in a counter‑clockwise direction. The extractor’s tapered design grips the bolt as it turns, pulling it out smoothly.
4. Monitor for Resistance: If you feel excessive resistance, stop and check alignment. Re‑positioning often resolves the issue without risking tool damage.
5. Clean After Use: Remove any debris from the extractor tip to maintain sharpness and prolong service life.
