Hello everyone,

I am currently facing the issue of needing to repair several stripped screw holes in a project. The materials involved are mainly wood and metal, sometimes in combination. I am specifically interested in knowing what repair methods are available to permanently and securely fix stripped screw holes so that screws can hold firmly again. It would be helpful if you could also discuss the advantages and disadvantages of the different methods and perhaps provide some tips on when each method is best suited. Thanks in advance!

Brief and to the point:

- Wood: Glue wooden dowels or fill with putty, then drill again.
- Metal: Use threaded inserts (Helicoils).
- For heavy loads, welding or replacing the part is often the best solution.

Not every method suits every case; check the material!

Hey everyone 😊

I want to add something that is often underestimated: additional products for screws, like thread lockers (such as Loctite), can provide extra security for minor repairs.

If the hole isn’t completely worn out, after a slight filling or the use of wooden dowels, these adhesives can give a really strong hold. This is usually enough for small household items.

So, if you don’t want to replace the entire hole right away, it’s worth trying this – it saves time and is very simple.

Patience is key here, because the adhesive needs to dry properly – at least 24 hours, otherwise, in my experience, it won’t hold well.

I agree with you, good things take time! ;-)

An important recommendation to add:

When using threaded inserts for metal, be sure to follow the exact drilling diameter and the pitch of the internal thread precisely. Mistakes here can quickly cause the inserts to fit loosely or become damaged.

For wood, I recommend cleaning and lightly roughening the fibers before gluing to ensure optimal adhesion and dowel fit. Choosing the right wood glue is also crucial: polyurethane glue is stronger than standard PV (photovoltaic) adhesive in terms of load-bearing capacity.

Finally, for structural or safety-relevant components, no compromises should be made, and any damage should be professionally repaired if necessary.
