The bolts are 'stretch bolts', in that they are initially torqued to a low figure, then tightened through a specified angle to achieve the required clamping force.

Generally they are re-usable, the normal recommendation is max three times, but this is general industry practice, not Fiat recommendation. The Fiat manual for the Panda does not mention having to replace.

Once they are out, check they are all the same length and all turn freely in their threads. If any are longer, or any have tight spots when turning, replace the lot.
