About the LC 020CD Compression Spring, 316 Stainless
LC 020CD 03 S316 is a stock helical compression spring supplied by Lee Spring in Type 316 stainless steel. The manufacturer’s data for this catalogue number gives an outside diameter of 0.25 in (6.35 mm) and a free length of 0.375 in (9.53 mm) — the two dimensions carried in the item title — wound from 0.020 in (0.51 mm) wire with squared and ground ends. The published rate is 6.36 lb/in (1.114 N/mm), and at a solid height of 0.094 in (2.4 mm) the spring carries a maximum load of 1.78 lb (7.92 N). Those proportions describe a short, stubby spring: the free length is only about one and a half times the outside diameter, so it works over a small stroke and is inherently stable without a guide rod or bore. The S316 suffix denotes the Type 316 stainless option, selected where corrosion resistance beyond standard stainless is needed.

Typical applications
With a 6.35 mm outside diameter and only 9.53 mm of free length, this spring suits short-travel duties inside small assemblies — button and plunger return, detent and ball-catch loading, or holding a contact or seal face pressed home. The squared and ground ends let it sit flat against a counterbore without a seat washer. Type 316 is the reason to choose it over a plain-stainless equivalent: washdown, marine-air and chemically exposed enclosures where a spring is awkward to reach for replacement.
