Core Bolt Co., Ltd.
Core Bolt Co., Ltd. has developed three products which can be a reliable solution to the chronic problems of bolt and nut loosening.A. CoreBolt – a one-direction bolt that applies physical pressure on both sides to prevent screw loosening, B. CoreLock – a theft-preventive bolt with an embedded lock on the bolt, and C. SpringLock – a spring locking bolt that stops nuts loosening from an opposite direction.Bolts/Nuts are considered as the essence of the mechanical industry, however the general fastening method in the past century has not significantly developed due to regulation such as standardization. Regulations in the industry should be strengthened in terms of safety; however it should be relaxed in the perspective of change and innovation. These opposite tendencies are similar to the characteristics of bolts and nuts that should be fastened, but be loosened as well. Compared to the existing methods, we sought to improve the wall plug mounting method and solve the nuts loosening issue. We have invented the physical locking device to bolts and nuts, and would like it to be evaluated as an innovative technology developed in terms of safety guarantee.
