Most likely a 20mm long M8 bolt with a 1.25mm thread pitch.

so if you start with the Mazda part number, the ones starting with a 9 are going to be JIS standard parts, and the size is in the part number
if its a normal part number, there will be some difference
for example, 9078-60-616B or more clearly 90786-0616B
9 = hardware, it'll be JIS standard, they do bolts, nuts, screws, washers etc
0786 = style of the part, this one happens to be a bolt with a captive washer, and no ransom note.
06 = diameter, M6
16 = length of the bolt, this one is 16mm
B = if there is a letter, it denotes the plating. blank is a gold zinc, B is Black (or dark)
since its a JIS standard part, we know an M6 is a 1.0 thread pitch with a 10mm head.
9994-00-801 is an M8 Nut, M8 is 1.25 thread, 12mm head, gold zinc...
the hard one is the M10, i think typically its a 1.25 thread, but Mazda uses 1.5 for the exhaust stuff
and again, if its an FD01-28-114 is a normal part number, so its somehow not a JIS standard

^^^Calling for an M10 fastener, specs the pitch as well, which is 1.5 standard (maybe less so in a non-metric environment). Other 10mm fasteners are available in fine and extra fine - mazda uses all 3 on these things - which is probably the only diameter on the car where it applies.
