How to choose the right thread repairing assortments

The basic selection parameter is the thread size (M) and pitch – for example M6x1.0 or M10x1.5. It is important to choose exactly the same size as the original thread.

When choosing, consider:

• the exact thread size you are repairing
• the type of material (aluminum, steel, cast iron…)
• frequency of use (one-time repair vs. regular work)

For standard use, a kit for one specific size is sufficient; for more universal use, multi-size kits are more suitable.

Where and how thread repairing assortments are used in practice

These kits are used wherever a thread is damaged and it is not possible to use a larger size:

• car repair shops (e.g. repair of threads in aluminum parts)
• maintenance of machines and equipment
• engineering and machine production
• common workshop repairs

The most common use is in soft materials such as aluminum or alloys, but they can also be used in steel, cast iron, or plastics.

How thread repairing assortments are used

The repair principle is always the same:

• drill out the damaged thread
• cut a new thread for the insert (with an STI tap)
• screw the insert into the hole
• break off the installation tang

The result is a new thread in the original size, which is often more durable than the original material.

Sets usually include:

• drill bit (for smaller sizes)
• STI tap
• installation tool
• tang break tool
• thread inserts

Use is possible both manually and by machine depending on the specific situation.

How does the selection continue?

In this category you will find:

• setss for specific metric threads (M2 to M24, various pitches)
• versions according to thread pitch (e.g. M10x1.25 / M10x1.50)
• multi-size kits (e.g. M5–M12 in one set)

When choosing, focus on:

• the exact thread size (M + pitch)
• the scope of use (single size vs. multiple sizes)

Thread inserts can also be supplied separately on request.
