A related by different question:
My instinct here, almost always, would be to err on the side of higher grades.
Rated for 2, put a 3 on.
One disadvantage with this approach is cost: higher grades, more money.
Other than higher cost, are there other disadvantages to using a higher grade
than absolutely needed?
Are there situations where the lower grade is preferable? E.g., if something's
going to fail under stress, youâ??d rather it be a grade 2 bolt than the
expensive component itâ??s securing.
