fitted bolt
A far as I was aware, "boulon ajusté" says it all, but since we have a definition for "boulon plein trou" I can only imagine we are in the presence of the belt and braces approach.
fitted bolt A stud or bolt that has been fitted to its mating hole so that the clearances between its unthreaded shank and its mating hole are extremely small. Either the hole is drilled and reamed true and square with the bearing surface and the bolt machined to fit the hole, or the bolt is premachined and the hole reamed to fit the bolt. Not to be confused with interference fit.

FITTED BOLTS
075-7.9.1 WHY AND WHERE THEY ARE USED. Fitted bolts are special bolts designed to maintain equipment alignment and/or resist high shear loads. These bolts have a smoothly machined shank which is larger in diameter than the bolt threaded portion. For some applications that do not require a precise fit, a bolt with cut threads can be used, as the unthreaded shank of these bolts is slightly larger in diameter than the threaded portion (bolts with roll-formed threads cannot be used as fitted bolts due to their reduced diameter shank). Bolt-studs could also be used for these applications; however, it is not common practice

Ah, I see now the Eyrolles def. says "Syn. Boulon ajusté".
