I’m looking for wheel bolts that have a head for a 15-key. Haven’t found something like this yet. Can someone help me? I have bolts M12 x 1.5 x 30 but only for a 17-key and this will make it a torture of 2 hours. Bolts for a 7-key is probably the norm but the 15-key does not suffer the safety either. Does anyone know where these wheel bolts are? Or do you have to have them made separately?
