Lang Tools Metric Thread Restorer Kit 15-Piece (M6–M12) with 8-Pitch File, Compact USA-Made Tray

The Lang Tools 2584 is a 15-piece metric thread restorer kit that repairs damaged internal and external metric threads from M6 to M12 using seven taps, seven dies and a multi-pitch restorer file.

Compact and made in the USA, this organized kit ships in a clear-covered styrene tray so you can see and store each tool securely. It combines the common metric sizes mechanics and fabricators encounter—M6 through M12—with an 8-pitch file, enabling you to clean and re-form threads on bolts, studs, and nuts without replacing hardware.

Which thread sizes are covered by this set?

This set includes the most frequently used metric sizes for general repair and maintenance across automotive, industrial, and home projects. Both the external rethread dies and internal rethread taps cover M6, M8, M10 (two pitches), and M12 (three pitches), letting you match the most common pitch variations.

• Dies: M6-1.00, M8-1.25, M10-1.25, M10-1.50, M12-1.25, M12-1.50, M12-1.75
• Taps: M6-1.00, M8-1.25, M10-1.25, M10-1.50, M12-1.25, M12-1.50, M12-1.75

How does the restorer file help with uneven or damaged threads?

The included restorer file has eight distinct pitch grooves so you can match the damaged thread’s profile and re-cut irregular or flattened threads by hand. It’s especially helpful when threads are corroded, burred, or partially stripped and a tap or die alone can’t fully engage.

• Pitches: 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.50, 3.00
• Use the file first to remove burrs, then finish with the matching tap or die for clean engagement

What materials and storage features should I expect?

Tools arrive in a high-impact styrene tray with a clear cover for display, identification, and safe storage. The durable presentation tray keeps every die, tap and the restorer file in place so you don’t misplace pieces between jobs.

• High-impact styrene tray with clear cover for visibility and protection
• Compact layout organized by size for quick selection
• Made in the USA construction and quality control

When should I choose this set over a single tap or die?

Pick this kit when you want a compact, go-to metric collection that covers both internal and external thread repair across several pitches. It’s ideal if you regularly repair fasteners of varying thread pitches or need a portable solution that avoids repeated purchases of individual tools.

• Best for shops, technicians, mobile repair, and DIYers who encounter varied metric threads
• Useful as an emergency repair kit in toolboxes or service vehicles
