Welcome to SMI’s Online Store, your source for industry‑trusted tools and publications for spring designers.
Our print offerings include the Handbook of Spring Design and Mechanical Springs by A.M. Wahl.
The Encyclopedia of Spring Design is now available as an annual digital subscription. A limited number of print components previously bundled with the encyclopedia—Fundamentals of Spring Design; Compression, Extension, Garter and Torsion Springs; and Other Types of Springs—are still available. Print copies of Tolerancing and Testing are no longer offered.
We also provide the Advanced Spring Design (ASD) software, developed in partnership with Universal Technical Systems (UTS). Standalone and network licenses are available. After purchase, UTS will send download instructions. ASD licenses are valid for one year; renewal rates vary by version.
Additional configurations—including an Excel Add‑in and the web‑based ASD Premium version—are also available. For details, contact us at info@smihq.org.
