Problem bolts were all from supplier A in the last two weeks
We have three bolt suppliers ( A, B, C ), and we were seeing problems at the bolt from supplier A only when we assembled bolts in the last two weeks.

Can I use the below expression to describe the problems

(1) The problem bolts concentrated at supplier A?
(2) The problem bolts fixed in supplier A.
(3) The problem bolts happened at supplier A only.

Thanks

Answer

None of your choices is appropriate and the original sentence is flawed.  The bolts with problems seemed to be  (or had a positive correlations with) ones supplied by supplier A.

Answer

1 is closest. I would say : the problem books came predominantly from supplier A.

The words you have chosen are very location connected.  However the statement is ambiguous about location.  We could be talking about the location of the bolts now,  or when the problems occurred etc.  However that is not really what you are trying to say.  So we can talk about where the bolts that were problems came from.

If you want to use locative adjectives,  you could be more specific :

The incidence of not failure seems to be concentrated in the bolts from supplier A.
