Parafusos de cabeça sextavada M10-1,5 x 60 mm | Aço liso classe 10.9 | Roscado parcialmente (75/emb.)

I needed heavy-duty bolts for a steel frame repair, and these M10s with the partial threads gripped perfectly in the pre-tapped hole without any binding. The hex head seated deep on my socket, so no stripping under high torque.

The threads were clean and started easily by hand, which saved time when I was bolting a heavy steel bracket to a machine base. These class 10.9 hex heads feel solid and took a good amount of torque without stripping.

The partial threading on these M10s makes seating them in a flange or blind hole so much easier, and the hex heads grab a socket cleanly every time. The 10.9 steel feels properly rigid without any flex when torquing down. Pack of 75 is a solid value for keeping on the shop shelf.
