Will a 1/4 inch bolt fit a 6mm hole?

The holes that are slightly large of 6mm are actually for 1/4″ bolts. As they say, the bolts are 1-1/4″ long. Typically this will be 1/4-20 unless there is an extraordinary need for strength. Since they are bolt-nut pairs, you may be able to substitute 6mm, but the 1-1/4″ length will still be essential.
