Spring stock ranges (Lee Spring): compression, extension and torsion OD, wire, free length, sample rates
What sizes do stock compression, extension and torsion springs come in (OD, wire diameter, free length), and what are typical rates? · Standard part · basis: Lee Spring stock-spring overview (stated ranges) and Lee product pages for sample parts (OD, wire, free length, solid height, rate, coils)
Also called: compression spring sizes, extension spring sizes, torsion spring sizes, lee spring stock sizes, spring wire diameter range, compression spring od range, spring free length range, lc 063g01s, lc 026bc08s, stock spring sizes od wire free length, small compression spring rate, torsion spring leg length

Notes
- What a Lee Spring stock catalog covers (its own overview page): compression springs OD 0.025 to 1.937 in, free length 0.025 to 6 in, wire 0.004 to 0.177 in; extension springs OD 0.063 to 2.0 in, free length 0.250 to 10.0 in, wire 0.007 to 0.207 in; torsion springs OD 0.105 to 2.141 in, leg length 0.375 to 4.25 in. Lee states over 25,000 stock designs. Materials: music wire (plated or coated) and passivated 302 / 304 / 316 stainless; heavy-duty compression also in oil-tempered MB wire. The page states no rate range, so none is given.
- The rows below the ranges are individual stock parts read from Lee's product pages (they are samples across the range, not a catalog table): the rate, solid height and coil counts are the page's. Compression rate k = G d^4 / (8 D^3 n) is on the springs page. Extension free length is measured inside the end loops. Torsion torque is the maximum at the stated deflection; the page for LTML 100J 04 M lists no rate.
- The LC 026BC 08 S page prints wire 0.03 in in its table and 0.026 in in the description; the part number's 026 and the description are used. LC 026EE 10 S: the page's 'ID' column is the hole it works in, so ID is left out for every row.
- Lee's printed catalog sections (extension and torsion PDFs) were also tried; their text came back scrambled across columns, so no row from them is used.
- No files: a spring's outline is a coil of wire whose pitch, end shape and hooks the pages do not print as numbers; the existing springs page has the envelope models.
