Extension Spring: OD 3.99 mm, FL 17.4 mm, Music WireStandard Extension Series (metric)Selection to Match Your Needs Lee Spring LEM080AC 02 M is a precision extension spring from the Standard Extension Series (metric) series, engineered for applications requiring reliable quality extension springs. This spring features a 3.99-mm outside diameter (0.157 inch) with 2.41-mm loop inside diameter (0.095 inch) and extends from a free length of 17.4 mm (0.685 inch) to a maximum extended length of 21.67 mm (0.853 inch). Made from Music Wire with a 0.79-mm wire diameter (0.031 inch), the spring delivers a spring rate of 8 N/mm (45.68 lb/inch) through its 16 total coils with an initial tension of 5.961 N (1.34 lb) for predictable extension behavior. The spring supports a maximum load of 39.901 N (8.97 lb) at full extension with a body length of 13.39 mm (0.527 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.
