stainless steel 316 clamp PAH-5271-TRIG-SS-316 is used by siemens windmills.
it's a special clamp that has a secondary lock.
the thing that makes it special is that siemens windmills wanted to have the clamp in stainless steel 316 quality ; which makes it more resistant to corrosion or rust. this is typically the case when it's high on a wind turbine and exposed to extreme weather conditions.
there is only one component that is not made of stainless steel 316, it's the little spring that holds the secondary lock, that is made of stainless steel 302
the composition of this material is below in a table
the clamp is used to close the service panel for the turbine engine.

here you see another model used on the cover of windmills, this one the customer wanted it to be white looking, because red can be seen by the eye better.
