    Chain ring bolts are fairly specific in length - I bought the £9 FSA bashguard and it came with extra long chain ring bolts. Other bash rings (esp metal ones) are less thick - with these you may be able to use regular ones.
    Top tip - make sure they are secure! I managed to lose 3 out of four of them in Morroco which was a right PITA as we didn't have the right size! Managed to cobble something together but is better to do it right in the first instance.

    Check the length of your current bolts if they worked with your bashring.

    Normal chainring bolts are shorter sometimes unless you fitted a bashring in place of an outer chainring and it's not a stupidly thick bashring like an E13 in which case you would have longer bolts.

    I've used a 10mm outer diameter/8mm internal diameter steel tube with M8 bolts through the inside of the tube as chainring bolts. Just measured the distance from one side to the other and cutted the four tubes with half a milimiter less. It works all the time but it's heavy compared to normal bolts.
