Yes, but that type is probably not suitable for marine use - or in use
where it MAY get exposed to salt water.

When you stick stainless in salt water you rapidly discover there more
to stainless steel than just the word. Salt water can rapidly corrode
the cheaper grades of stainless steel.

A quick check with google says if your stainless steel is magnetic, it's
probably 304 grade and is not suitable for use in salt water environments.

Another gotcha is don't mix stainless steel fixings with aluminum. The
dissimilar metals will start to galvanic corrode the moment it gets an
electrolyte on it - i.e. salt water.

Nasty stuff salt water, wrecks all sorts of things.
