steel,
2. Carbon-steel bolts, nuts, and washers shall be used where mating parts are not stainless
steel, and
3. Anti-galling compound (e.g., Loctite Anti-Seize ® ) shall be applied where stainless steel
bolts are used, except if Nitronic 60 materials are used.
G. All fasteners used for structural and pressure boundary applications shall be provided with
CMTRs. All remaining fasteners shall be provided with a manufacture’s Certificate of
Conformance.
