Extension Spring: OD 3 mm, FL 19.99 mm, Stainless Steel

Instrument Extension Series (metric)

Precision Springs for Precision Products.

Lee Spring EIM030C 05 S is a precision extension spring from the Instrument Extension Series (metric) series, engineered for applications requiring reliable quality extension springs. This spring features a 3-mm outside diameter (0.118 inch) with 2.39-mm loop inside diameter (0.094 inch) and extends from a free length of 19.99 mm (0.787 inch) to a maximum extended length of 55.25 mm (2.175 inch). Made from Stainless Steel with a 0.3-mm wire diameter (0.012 inch), the spring delivers a spring rate of 0.081 N/mm (0.464 lb/inch) through its 47 total coils with an initial tension of 0.276 N (0.062 lb) for predictable extension behavior. The spring supports a maximum load of 3.14 N (0.706 lb) at full extension with a body length of 14.61 mm (0.575 inch). The spring features Random loop position and Passivate per ASTM A967 finish for optimal performance.
