As the veterans returned from World War II to Nashua Corporation in 1946, the board of directors voted to waive interest on all military loans.

This meant that interest on loans procured by veterans before the war, from the time they entered the armed forces until they were released, would not have to be paid.

The credit union erected a new one-story brick office building with adjoining parking lot, which was dedicated in September 1968.

The bylaws were amended in 1968 to include members of the immediate families and employees of other Nashua Corporation facilities outside the state of New Hampshire.

In September 2003, Triangle Credit Union opened its first in-store branch and was the third financial institution to do so in a BJ's Wholesale Club.
