Standard Extension Series (metric)

Selection to Match Your Needs

Lee Spring LEM063A 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-mm outside diameter (0.118 inch) with 1.73-mm loop inside diameter (0.068 inch) and extends from a free length of 13.49 mm (0.531 inch) to a maximum extended length of 16.46 mm (0.648 inch). Made from Music Wire with a 0.64-mm wire diameter (0.025 inch), the spring delivers a spring rate of 7.51 N/mm (42.88 lb/inch) through its 16 total coils with an initial tension of 4.19 N (0.942 lb) for predictable extension behavior. The spring supports a maximum load of 26.2 N (5.89 lb) at full extension with a body length of 10.8 mm (0.425 inch). The spring features Inline loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.

Extension Springs: Standard Series

The 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.
