These are Peugeot 205 Bumper Fixing Bolts which are made in stainless steel, and include 4 short bolts and 4 long bolts, plus 8 stainless steel M8 nuts. These are direct fit replacements for the Peugeot ones which are no longer available, and which were never made in a stainless steel. Whilst they are not identical to the original ones, they fit the same and work the same, plus with the added benefit of never rusting again. These are replacements for Peugeot part numbers 742947 (7429.47) and 742948 (7429.48).
Anyone who has attempted to remove their bumpers or mounting brackets will know the struggle of them snapping or churning the plastic channel up within the bumpers when undone. These are an extremely cost-effective replacement, given Peugeot charged over £7 for a single bolt.
