I took the black factory bolts to Home Depot to determine what size was required but they didn't stock the required size. (Factory: 2 x 6mm-1.0 x 50 mm plus 2 x 6mm-1.0 x 60 mm replacements needed to be at least 5mm longer). I then went to Lowe's and they had them, but only zinc plated. I would have preferred stainless steel. Tip: Depending on how thick your cross bars are, you can save a little by buying only two 65mm long bolts to replace the factory 60 mm bolts, and use those to replace the factory 50mm long bolts.
