Standard Extension Series (metric)

Selection to Match Your Needs

Lee Spring LEM035A 03 S 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 2.29-mm loop inside diameter (0.09 inch) and extends from a free length of 15.49 mm (0.61 inch) to a maximum extended length of 31.24 mm (1.23 inch). Made from Stainless Steel with a 0.36-mm wire diameter (0.014 inch), the spring delivers a spring rate of 0.231 N/mm (1.32 lb/inch) through its 32.3 total coils with an initial tension of 0.444 N (0.0999 lb) for predictable extension behavior. The spring supports a maximum load of 4.076 N (0.9163 lb) at full extension with a body length of 10.92 mm (0.43 inch). The spring features Random loop position and Passivate per ASTM A967 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.
