The round hook is a hook shape that is resistant to breaking and deformation.
The hook that looks like a photo is called a "drawn round hook." It has a hook integrated into the body, making it resistant to issues such as breakage and deformation. The hook and body are manufactured separately, and typically, a thicker wire diameter for the hook is chosen compared to the body. While increasing the strength of the hook, the spring constant of the body can be freely designed, which is an advantage of the "drawn round hook." (Please also see the related links.) Our company handles the design and prototyping of tension springs. Our technical staff will respond carefully, so please feel free to consult us if you have any concerns. Tsurugaoka Spring Co., Ltd.
