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!

Hi SeJulio,
It feels like everyone has at some point stripped screw holes, and that’s really frustrating! 🙂
A simple method that often helps is using wood filler or repair putty for wood. You fill the hole, let it dry thoroughly, sand it smooth, and then drill again. It’s quick, inexpensive, and holds well under normal stress.
For metal parts, there are usually two options: either use threaded inserts (Helicoils) or fill the hole by welding and then drill again. Threaded inserts are very handy because they basically create a new, stable thread inside the old hole.
As a rule of thumb: analyze the material carefully first, then choose the method – no repair fits all cases.
Good luck! 🚀

Hello SeJulio,
to address your question as precisely as possible, I would like to know the sizes of the screws and the types of loads involved. Repair methods vary significantly depending on whether you are dealing with furniture, mechanical parts, or structural connections.
For wood, a reliable method is to use wooden wedges or dowels. The damaged hole is first cleaned up, then a suitable wooden dowel is glued in and subsequently re-drilled. This provides a secure anchoring.
A more advanced solution for higher loads is the use of metal inserts or threaded bushings (known as Helicoils in metal parts). The damaged hole is drilled out, a thread is cut, and the insert is screwed in, creating a new internal thread.
For metal—depending on whether it is cast iron or steel—welding or installing weld nuts may be appropriate. However, this requires technical expertise to avoid distorting or weakening the component.
If you can provide more details—material, screw diameter, type of load—I’d be happy to go into further detail.

I know how frustrating stripped screw holes can be—especially when you think you’ve done everything right and suddenly nothing holds anymore. I recently tried to repair several wood screw holes that were completely damaged.
What I learned is that it’s worth cutting out or drilling out the damaged area completely and then gluing in a properly sized wooden dowel. Patience is key here because the adhesive needs to dry thoroughly—at least 24 hours—or in my experience, it won’t hold well.
I can only confirm that. By now, this has become my standard method since it saves me a lot of stress and the results remain stable even after a long time.
Good luck with your repair!

Hello,
I would like to add some details about repairing metal screw holes. For stripped threads or damaged holes in metal parts, thread inserts—such as Helicoils or Keenserts—are the most common repair solution.
The process is as follows:
1. The damaged hole is drilled out to remove any remnants.
2. A new internal thread is cut with a suitable tap.
3. The thread insert, made of hardened steel, is screwed in using a special tool.
This method nearly restores the original strength and is especially suitable for heavily loaded parts—for example, engine blocks or frameworks.
One disadvantage: special tools and precise work are required; otherwise, the fit will not be correct. Also, this repair is not easily done with basic DIY tools.
For metal parts subject to low stress, alternatively welding the hole closed and then re-drilling may be helpful, provided you have the necessary skills.
Hope this helps!

Hello everyone,
I would like to return to the topic of working with wood, as there are actually different methods that suit various load conditions.
Besides wooden dowels, which have already been mentioned here, there is also the option of filling the hole with wood glue and wood shavings. In this method, finer shavings are mixed with glue, the hole is packed, dried, and then re-drilled. However, this often results in joints that are less durable than those made with wooden dowels.
For heavily loaded joints, I recommend fully refining the damaged hole, for example with a Forstner bit, to clean it up, and then gluing in a matching wooden tenon or plug made from the same wood. After curing, the hole can be drilled again—this provides a stable and long-lasting repair.
Do you have specific requirements regarding load or visual aspects? This strongly influences the choice of method.
