Viti a testa esagonale M20-2,5 x 110 mm | Acciaio classe 10.9 zincato | Filettatura completa (55 / Pacco)

The zinc plating on these fully threaded M20 bolts looks even and consistent across all 55 pieces, which is exactly what I needed for a heavy machinery rebuild.

The hex heads on these M20 bolts fit my socket perfectly without any slipping, even when torqued down tight. That class 10.9 rating gives me confidence they won't strip under heavy machinery loads. Solid fasteners for the price.

Needed a handful of these for mounting a jig on a heavy-duty press, and the plating held up perfectly against the wrench. The 10.9 grade gives them solid clamping force without stripping — exactly what I needed.
