Extension Spring: OD 3.51 mm, FL 24.51 mm, Music WireStandard Extension Series (metric)Selection to Match Your Needs Lee Spring LEM050AB 04 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 3.51-mm outside diameter (0.138 inch) with 2.49-mm loop inside diameter (0.098 inch) and extends from a free length of 24.51 mm (0.965 inch) to a maximum extended length of 41.81 mm (1.646 inch). Made from Music Wire with a 0.48-mm wire diameter (0.019 inch), the spring delivers a spring rate of 0.59 N/mm (3.37 lb/inch) through its 40 total coils with an initial tension of 1.77 N (0.398 lb) for predictable extension behavior. The spring supports a maximum load of 12.01 N (2.7 lb) at full extension with a body length of 20.83 mm (0.82 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance. Extension Springs: Standard SeriesThe Lee Spring Standard Extension Spring Series includes a wide range of size and rate combinations and in both inch and metric sizes. Standard Series springs are available in Music Wire, Type 302 Stainless Steel and Type 316 Stainless Steel. Metric Series springs are available in Music Wire and Type 302 Stainless Steel. The Music Wire springs are provided with a plating finish for light corrosion resistance. The Type 302 Stainless Steel springs are passivated, while Type 316 Stainless Steel springs are passivated and ultrasonically cleaned. Lee Spring's Stock Extension Springs are supplied with full diameter loops (either to machine or crossover center style) at a random position with the exception of Metric Extension Springs which are specified to meet DIN Standards.
