Do the rear brake caliper bracket bolts require a 6300-16 16mm 12 Pt male bit? on 2007 Volkswagen Eos

Need to remove the caliper brackets before the rotors can be removed and replaced. There are two bolts that have what appear to require a 16mm 12 point male bit but want to be sure before I purchase a $30 tool.

Further investigation found the proper tool is a 14mm Triple Square. Needs to be super short. Standard bit from Snap On is too long.
