I have a thread here I can't find a standard size for, it is off of my bicycle (an older non-high performance Norco mountain bike, it was made in Taiwan). The nut holding the crankshaft on is stripped, the threaded rod is 0.385 inches (measured with a digital caliper) and looks to be about 20 TPI (sorry don't have a thread gauge at home). A 3/8 fine nut will not fit on (which is what my boss thought it would be looking at the stripped nut, though the stripped nut did fit on a 3/8 fine bolt). Anyone have an idea on the thread size I need so I can buy or make a new nut? Ken
