Great for 3D printed enclosures
I use these in every single 3D printed enclosure I design and they are perfect. Just finished off a bag of M3's and I've ordered some M4 and M5

Génial, se fixe simplement avec un fer à souder. Impossible de le retirer même en forçant. L'emballage est de très bonne qualité et des schémas avec toutes les cotes sont imprimés dessus.

Come sempre gli inserti filettati Ruthex si confermano un ottimo prodotto. Io li utilizzo in stampe 3D, e svolgono bene il loro lavoro. Una volta inseriti a caldo è davvero difficile che si tolgano. Prodotto consigliato
