M12 x 1.5 about 39mm long and with about 19mm of thread.Does anyone know the size of security bolts for SLK with 18'' AMG wheels aftermarket or the original part number??
Thanks all of you!!!I simply assumed the OP wanted to locking bolts for an R171 (judging on the profile). For the sake of being more complete, let me add (I couldn't edit my previous posting) the info for the other SLK types as well... The OEM part numbers are:
In Germany, a set costs a little more than EUR60 incl VAT.
- R170/R171 (hence, M12 bolts): B66470154
- R172 (having M14 bolts): B66470155
