Las tuercas son excelentes, calidad y tamaño exactos. Lo que no está bien es la descripción del artículo, ni la traducción. Habla de "paquetes" y nadie respondió mis preguntas antes de comprar. En la página del fabricante Bolt Base los "paquetes" contienen 10 unidades, y el costo es acorde e incluso más barato. Yo compre 5 "paquetes" y me enviaron 5 tuercas, a un precio superior a 50 tuercas en su pagina. Compre por amazon x que Bolt Base no envía a Argentina, pero me siento estafado

The square nuts are fine, but if I wanted to wait six weeks for delivery from China I would have ordered from Alibaba.Amazon needs to clearly mark Chinese vendors so I can avoid them!

They fit and cannot see any difference with the ones that came from Prusa.While waiting for these to arrive I managed to eject enough square nuts from the old partsso did not yet need them after all.

These are the correct square nuts for the Prusa MK2, Mk2s with and without the MMU. Glad I found them, as most available here in the U.S. are too thick.

These are the same dimensions, including thickness as the square nuts used on the Prusa 3d printer and several folks have created parts that use this exact size, so being able to obtain in the U.S. was a plus.
