Specializing in screw loosening prevention processing, "Tōkai Lock Co., Ltd." has had a strong start two months after opening!
Tokai Rock, a group company of Koyama Co., Ltd. located in Numazu City, Shizuoka Prefecture, relocated its headquarters and factory at the end of last year and is now operating at full capacity with new equipment.
At Tokai Rock, we protect our customers' screws from "loosening" and "deflection" over time by applying adhesive to the screw parts. We accommodate small lots, a variety of products, and short delivery times. Additionally, as a certified factory of the major adhesive manufacturer Henkel, we provide comprehensive support for environmental surveys and material certifications.
Please feel free to contact the Development Sales Department of Koyama Co., Ltd. at ☎03 (3363) 3711.
