Extension Spring: OD 4.5 mm, FL 15.9 mm, Music WireStandard Extension Series (metric)Selection to Match Your Needs Lee Spring LEM063B 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 4.5-mm outside diameter (0.177 inch) with 3.23-mm loop inside diameter (0.127 inch) and extends from a free length of 15.9 mm (0.626 inch) to a maximum extended length of 24.94 mm (0.982 inch). Made from Music Wire with a 0.64-mm wire diameter (0.025 inch), the spring delivers a spring rate of 1.73 N/mm (9.88 lb/inch) through its 16 total coils with an initial tension of 2.611 N (0.587 lb) for predictable extension behavior. The spring supports a maximum load of 18.282 N (4.11 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 SeriesThe Lee Spring Standard Extension Spring Series includes a wide range of size and rate combinations and in both inch and metric sizes.
