We also accommodate hook shapes that are outside of JIS standards.
Material: Piano wire type A, SWP-A Wire diameter: Φ3.5, right hook only Φ5.0 Both hooks are shapes not specified by JIS standards. The left hook is shaped like a reverse round hook, which is pinched inward before the U-hook is raised. The right hook is a longer version of the pinched round hook. A thicker hook than the body is processed to prevent it from slipping out and is incorporated inside the body. (For information on the pinched round hook, please refer to the related links.) Our company handles the manufacturing, design, and prototyping of tension springs. Please feel free to consult us if you have any concerns. Tsuruoka Spring Co., Ltd.
