Socket extractor set Tvardy 11-piece 6–19 mm CR-MO for rounded or broken bolts

The Tvardy 11-piece socket extractor set 6–19 mm is a purpose-built tool kit for removing rounded, damaged or broken bolts and screws. Made from chrome-molybdenum (CR-MO) steel, the stepped extractors are shaped to bite into damaged fastener heads, allowing removal using a socket or wrench. The set covers common metric sizes from 6 mm up to 19 mm, providing a compact selection for automotive, machinery and general maintenance tasks where safe, controlled fastener extraction is required.

Advantages

The chrome-molybdenum construction offers increased strength and resistance to deformation when applying high torque. Stepped extractor geometry ensures progressive bite into rounded or damaged heads to minimise slipping. The broad size range from 6 to 19 mm reduces the need for additional tools and enables efficient work across multiple applications. The set is compatible with standard sockets and wrenches, making it easy to integrate into existing toolkits.

Suitable for

• Removal of rounded or damaged bolts and screws
• Automotive repair and maintenance
• Industrial and workshop machinery servicing
• General maintenance, assembly and disassembly tasks

Key specifications

• Size range: 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 17 mm, 19 mm
• Material: chrome-molybdenum steel (CR-MO)
• Type: stepped socket extractors for rounded/broken fasteners
• Compatibility: designed for use with standard sockets, ratchets and wrenches

How to use

Select the extractor size that most closely matches the damaged fastener. Place the stepped extractor over the fastener head and attach a matching socket. Apply steady, controlled torque using a ratchet or wrench so the extractor can bite into the damaged material and rotate the fastener out. For tightly seized or rusted fasteners, apply penetrating lubricant and allow it to soak before attempting extraction. Avoid sudden impact or excessive force that could further damage the fastener or the extractor.

Usage recommendations

Use with appropriate personal protective equipment and standard workshop safety practices. Inspect extractors for wear before use and replace any that show significant deformation. For corroded or severely seized fasteners consider combining penetrating oil, heat (where safe) and gradual torque application to improve extraction success.
