Extension Spring: OD 4.5 mm, FL 54.99 mm, Music WireStandard Extension Series (metric)Selection to Match Your Needs Lee Spring LEM060B 12 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 3.28-mm loop inside diameter (0.129 inch) and extends from a free length of 54.99 mm (2.165 inch) to a maximum extended length of 103.76 mm (4.085 inch). Made from Music Wire with a 0.58-mm wire diameter (0.023 inch), the spring delivers a spring rate of 0.284 N/mm (1.62 lb/inch) through its 85.8 total coils with an initial tension of 1.868 N (0.42 lb) for predictable extension behavior. The spring supports a maximum load of 15.702 N (3.53 lb) at full extension with a body length of 48.44 mm (1.907 inch). The spring features Random loop position and Zinc Plate and Bake per ASTM B633 finish for optimal performance.
