Back in 1931, we established our first company Hamadaya Shoten and joined local business in Nagasaki.
Nagasaki is famous for its shipbuilding industry and back at that time,
wooden made ship were still major, we provided wooden screws and ship nails to local wooden ship manufacturers and that was the beginning of Hamax.
We’ve been providing bolts and nuts products to ship manufactures up to today,
and it is one of our tasks to dedicate ourselves to the shipbuilding industry and support its development.

Bridge and Construction

Our anchor bolts are all produced by thread rolling processing and with this method
these are much stronger compared to the products made by cutting threads.
High quality and smooth fitting nuts enhance workability during the operation on the construction sites as well.
