Company information
Kōmuro Seisakusho Co., Ltd. is a manufacturing and sales company specializing in tapping screws. We produce a wide variety of screws based on "JIS standard products," including the powerful anti-loosening screw "Motion Tight," which achieves stability against loosening and breakage, and the "Three Tight," which has a rice ball-shaped (triangular) body. We also offer various surface treatment processes. Please feel free to consult with us. By transforming it into a "smile" that is neither "+" nor "−," we add the joy of "discovery" and design the fun of "sharing the joy when finding small surprises" with others through our 【Smile Screw】.
