Effortless extraction of broken bolts
- Wide thread capacity range: You extract damaged screws and broken studs covering sizes from M3 to M24 with complete control.
- Firm and damage-free grip: The finely fluted left-hand taper bites securely into the drilled core without damaging the internal host threads.
- Reliable Kukko 49-B set: You drive each extractor smoothly using a standard tap wrench or open-ended spanner via the square drive.
With the Kukko 49-B screw extractor set, you remove broken bolts, studs, and screws with precision, keeping the surrounding internal threads fully intact. This 6-piece set covers thread sizes from M3 up to M24 (3 mm to 24 mm). After drilling a pilot hole, the finely fluted left-hand taper bites securely into the fastener to unscrew seized or stripped components smoothly. Thanks to the sturdy square drive, you can easily operate each extractor (49-1 through 49-6) using a standard tap wrench or open-end wrench, saving valuable time during repairs and machinery maintenance.
