Supporting people’s everyday lives through a belief in our potential.
Thank you for taking an interest in our website.
My name is Kazuta Oku, President of O&K Company.
We are a highly specialized, niche manufacturer that produces cold heading wire, which is used in the manufacture of screws, nuts, bolts, and other metal parts. We have 400 employees in Japan and another 200 employees overseas to produce wires necessary to make flexible, smooth, and round parts.
As a company that manufactures products less obvious from the point of view of consumers, many probably do not know our name. Nevertheless, believing in the infinite potential of wire manufacturing, we have continued to support people’s everyday lives from behind the scenes throughout our roughly 100-year history.
