Not an aviation piece of equipment, but was pulled from a car tire on the highway here in Canada. It measures about 6 cm from end to end, one end is a chromed tip, looks similar to a grease nipple, the other end, although damaged, is threaded and appeares to have a bolt, up against a gear. The thread is made of steel and the top end is a soft chrome. Again, found on the highway, caused a flat tire. Mechanic had no idea what it was when he pulled it out
Any ideas?
