can anyone give me advice were can I buy this type of screws?

Thank You in advance!

 

Dealer if available. Likely the whole bag.

 

really?, do you know anywhere else where I can buy them in the internet?

 

I'm assuming you have one. If you do, I'd take one to the your auto supply. Find out what size the bolt part and also the tort. If you have that information you could most likely order either from an auto supply, or some online companies that specialize in bolts, screws, and fastners.
