Yeah all the bolts were fine, gripped without any problems. All was protected with some copper grease too.
They aren't longer bolts, the spacers are "system B" meaning they come with bolts to fit them to the hub. Then you use your normal wheel bolts to fit to the spacer.
Both spacers are off now so can't tell if the bolts were protruding through the hub and catching something.
- I read on here before about someone having to get spacers "machined" to fit - what was all that about? :S
These are genuine FK Hubcentrics for the Clio direct from FK themselves so can't understand why it's not a "simple fit"
