My son has a Schwinn mountain bicycle and has lost one of the bolts to the faceplate that clamps the handlebar to the stem.
Now I dealing with this by phone, and I'd like to purchase a replacement on my way home. But a trip home to unscrew the remaining bolt and then go to the hardware store to get a replacement can't really be done in one day before the store's closing.
Is there a standard part that typically used for this application that I can buy on the way home without having a sample to match?
Its a Schwinn Traverse 26 inch mountain bike model S2713TR with two sunken Allen head bolts holding the faceplate, one of which is missing
