Made from Music Wire with a 1.4-mm wire diameter (0.055 inch), the spring delivers a spring rate of 0.97 N/mm (5.54 lb/inch) through its 16 total coils with an initial tension of 8.501 N (1.911 lb) for predictable extension behavior. The spring supports a maximum load of 57.115 N (12.84 lb) at full extension with a body length of 23.75 mm (0.935 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.
