Screws
It's a list of parts, so not a lot of context. However, I found this description:
"A shear head screw 10 (Fig. 3) comprises a first (screw) head 14A and a second head 14B coupled by a shear neck 16 so that the screw can be tightened by the first head 14A until the screw shears at the neck 16 leaving the second head 14B and a threaded stem 12 tightened to a predetermined torque determined by the shear force."
I also found an image:

I tried some names based on that, but cannot find an equivalent in PT-BR.
Thank you!

| Nick, obrigado. Então, eu tentei esse no começo, mas encontrei também imagens que não correspondem ao que eu preciso. Acredito que vou acabar ficando com esse mesmo. |

: "These screws are dome security fasteners. The security feature is the hexagonal shaped section on the top of the bolt. This is fully tightened with a standard spanner or cross recess driver until the pressure applied surpasses the maximum torque limit..

basically it is tightened until the head breaks (shears) off. It is used on steering column locks for security.
