Company information
FASCO Trading Co., Ltd. has been primarily engaged in the export of 100% Japanese-made bolts and nuts since its establishment in 1978. However, starting around 1989, we began importing and selling resin products, and in 2005, we launched trilateral trade from Southeast Asia to Europe and the United States, truly engaging in borderless business activities. The name FASCO embodies two meanings: FASTENER COMPANY (a company dealing with screws and fastening parts) and FASTEN COMPANY (a company that connects businesses). True to our name, we have focused on the sale of screws and facilitating smooth business transactions between companies since our founding. From importing clothespins to selling aircraft parts, we now handle over 200 items. As we adapt to changing times, we aim to expand our connections with companies around the world. Moving forward, with "good causes lead to good results" as our motto, we will consider environmental conservation in all aspects and contribute to environmental improvement, ensuring that we can hand over the wonderful Earth environment that nurtured us to the next generation worldwide.
