Offers material strength and consistent resilience for reliable long term function inside locksets. Key features and benefits Multiturn support options: Available in five torsion spring types with different numbers of support coils to suit varied handle mechanisms and load requirements. The support coil design evens out load distribution and increases cushioning to reduce performance degradation from shocks or vibration. Wire options for specific requirements: Three flat wire types and two round wire types are offered. Flat wire has a larger cross section for greater resistance to deformation under pressure or tension. Round wire provides a stable structure and even load distribution for smooth, consistent action. Durable carbon steel construction: strength and hardness provide wear resistance and reliable resilience under repeated use. Surface finish is smooth and burr to reduce friction within the mechanism. Precision winding and pitch: Uniform coil pitch ensures even torsion distribution for stable action and accurate positioning of the handle during opening and closing. Broad compatibility: Multiple shapes and coil options cover a wide range of door lock designs, making it suitable for internal and replacement jobs.
