To help you with your French the words should be:

"Merde!"  "Putain!" "Nom de Dieu!" "La Vache!"

It happens to us all and very annoying too. Although I've found the right socket/spanner/screwdriver/Allen key helps.

Ha, think you have it hard try the Philips screws that hold my bike together and thank god I can change to Hex bolts.

If you're talking about a damaged internal hex bolt ?

Buy some cheap 'star-hex' bits.

Find the size that doesn't quite fit into the damaged 'hex' and tap it fully in with a hammer.

Usually works.

A lot of fixings on bikes are made of something resembling 'cheese' and require extreme care with good quality tools when undoing.

Replace damaged one with bolts with a minimum strength of 8.8 (10.9 is better) or A-2 if using stainless.
