Although it was used for 5 mm thick aluminum bar, it could be used without problems. I think that it is a good product.
Repair of aluminum hanging door

I purchased a tap of minor inch size because it became necessary quickly. Threading work was possible without any problem especially for aluminum material. It was a cheap product, but it was very useful for repairing the pulley of the hanging door.
