Cornwall is a professional fastener manufacturer since 1978. We started at Kaohsiung City and were producing smaller hex and square nuts such as sizes under ¼. At 1980, we moved to our current location and equipped more forming machines for producing bigger size nuts up to size 5/8.
At that same time, we were developing methods of forming pipe nut. After couple years promoting we were, and still are in the leading position of making steel pipe nut and with non-ferrous material such as brass, copper, silicon bronze and aluminum. These couple year, we were also developing markets for screws/bolts and special parts (by machining, stamping, die casting per samples or prints.)
