	Note that some grades of SS bolts may seize over time with the extreme temperatures; the only way to remove them is to apply pressure until they shear, then they will need to be renewed (removal will be necessary once a year for MOT if you are fitting a CRP). If fitting a CRP, normal steel bolts will be fine as the constant removal-refitting is enough to keep them from rusting up. ~~also~~ use of copper grease can help prevent seizure.
