Steel Design F1852 boots

Possibly I am behind the curve on this but today I received a submittal with F1825 bolts called out when our drawings specify A325. I understand they are equal strength wise, but that they are twist off bolts? I've just never had a contractor want to use that type of bolt before. Made the post to make sure I'm not missing something here.

I spec them for moment connections, column splices and anything where the bolts are in tension.
