as above i want to put the fogs back on front bumper of my k reg wrx but have no bolts and i would like to no the correct size of these if anyone can help thanx

 

M6 x 30, buy stainless.
Ebay, or look on www.yell.com, enter "Bolt and nut stockist" and then go to your chosen one and ask for some, I have two ordinary socket heads and one with a security pin, on mine.

Good idea to get some washers too, penny washers also in stainless are worth it.
