Extension Spring: OD 3.51 mm, FL 11.1 mm, Music WireStandard Extension Series (metric)Selection to Match Your Needs Lee Spring LEM070AB 01 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 2.08-mm loop inside diameter (0.082 inch) and extends from a free length of 11.1 mm (0.437 inch) to a maximum extended length of 13.46 mm (0.53 inch). Made from Music Wire with a 0.69-mm wire diameter (0.027 inch), the spring delivers a spring rate of 11.1 N/mm (63.38 lb/inch) through its 10 total coils with an initial tension of 4.47 N (1.005 lb) for predictable extension behavior. The spring supports a maximum load of 30.693 N (6.9 lb) at full extension with a body length of 7.82 mm (0.308 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.
