Compression Spring: OD 2.4 mm, FL 7 mm, Music WireInstrument Compression Series (metric) Compression SpringsPrecision Springs for Precision Products . Lee Spring CIM040BC 03M is a precision compression spring from the Instrument Compression Series (metric) series, engineered for applications requiring reliable performance in moderate-load scenarios. This spring features an 2.4-mm outside diameter (0.094 inch) with a 2.8-mm hole diameter (0.11 inch) and extends to a free length of 7 mm (0.276 inch), making it ideal for instruments and assemblies where consistent and precise compression characteristics are critical. Made from Music Wire with a 0.4-mm wire diameter (0.016 inch), the spring delivers a spring rate of 3.894 N/mm (22.233 lb/inch) through its 8.5 active coils out of 10.5 total coils for predictable deflection behavior. The spring compresses to a solid height of 4.6 mm (0.181 inch) while supporting a maximum load of 9.63 N (2.164 lb) at full compression. The spring has Squared ends and a Zinc Plate and Bake per ASTM B633 finish for optimal performance. About the Compression Spring Instrument SeriesThe Lee Spring Instrument Series includes a wide range of size and rate combinations in a smaller, highly precise spring design. Selections are sorted in ascending order to mating hole/bore diameter sizes. Instrument Compression Springs are available in both inch and metric series. Inch 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 made from coated wire or 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. Lee Spring Instrument Compression Springs feature squared ends. A squared end, also called a closed end, is made by reducing the coil pitch of the ends to zero. Squareness influences how a force produced by the spring can be transferred to adjacent parts Instrument Compression Series (metric) Compression Springs have useful applications in various industries, including:
