TOPTUL 5PCS Screw Extractor Set – CR-MO for Broken Studs and Bolts

The TOPTUL JGAW0502 5PCS Screw Extractor Set is designed for removing broken screws, bolts, socket screws, and damaged fasteners in workshop and maintenance applications.

The set includes 5 extractor sizes made from Chrome Molybdenum Alloy Steel and heat treated for practical durability. The aggressive left-hand spiral design helps the extractor grip the damaged fastener during removal.

The spiral flutes help the tool bite deeper into the broken screw or bolt, and the grip increases as resistance increases. Each extractor also has a square drive end for use with a tap wrench.

This set is a practical choice for automotive maintenance, equipment repair, and mechanical workshop use.

What Is a Screw Extractor Set?

A screw extractor set is used to remove broken or damaged screws and bolts that cannot be removed with standard tools. A correct pilot hole is drilled first, then the extractor is inserted and turned counter-clockwise to help remove the fastener.

How to Use the Set

1. Select the extractor size that matches the broken screw or bolt.
2. Drill the correct pilot hole according to the size guide.
3. Insert the extractor into the hole.
4. Use a tap wrench on the square drive end.
5. Turn counter-clockwise gradually.
6. Avoid sudden force to prevent breaking the extractor inside the screw.
7. Clean the thread area before installing a new fastener.
