Great tool
It could do with been a little thicker. However it’s a great product. I deal with both metric and imperial threads it’s a very easy check

Ideal from the land of the bright idea...
I had doubts if the M2.5x45 chinese knock off taps were actually that thread. They aren't This item whilst a little over produced should be good for pretty much all the small screws currently employed in everything from Glasses to Model Steam Locomotives. It is moulded from a half decent plastic which is it's only negative. It would be too easy to damage the threads if you use a damaged bolt that you wanted to check. It fits in my Tool box and being flat can stand to one side. I didn't expect much but it is better than the price indicates.

Très pratique !
J'ai differentes jauges de filetage, mais celle-ci est particulièrement utile par son principe et sans légèreté. En un clin d'œil ont peut vérifier diamètre et pas. Seule contrainte : elle est en plastique, donc il faut en tenir compte et ne pas forcer si la tige filetée n'entre pas de façon fluide.
