UJEN Development Co., Ltd. was named with the following four folds of meanings:
"U" stands for Uniqueness
"J"  stands for Jaunty, as in richness in colors, and in liveliness.
"E"  stands for Esthetics and Ergonomics in design
"N" stands for Noble, in helping customers elevating values.


There was a saying that, no matter what one’s role is, it is always an important role; So, for a machine, even a small screw, it would have an impactful effect on the whole. Therefore, the quality of screws, the handling of knobs and esthetics in design, all has effects on the overall quality of machines. To this end, we strive to develop comfortable, esthetically pleasing, durable and special hardware accessories, all in the name of elevating competitive edge for our customers!



With industry-unique styling and color scheme in design, every product type has 4 types of styling esthetics (Concave, Plane, Convex, and Dot), and 4 colors for each of inner circle and central circle, which offers almost 200 combinations, we give you unique styling to your products while optimizing your competitive edge!
