Compression Springs Wire Dia 1.5mm OD 16/17mm L 10-200mm 304Stainless Steel

Match the outer diameter (OD) to your spring pocket or bore — choose 16mm OD if your bore is 16–16.5mm, or 17mm OD if your bore is 17–17.5mm. Then select a free length that gives you adequate compressed travel for your mechanism. If you are unsure, measure the available cavity depth and the required stroke, then add them together to estimate the minimum free length needed.

Load capacity depends on the specific free length and OD combination you select. Shorter springs with the same wire and OD will generally have a higher spring rate (stiffer). For precise load and deflection data for a specific variant, contact us to confirm before ordering for load-critical applications.

Yes. 304 stainless steel provides solid resistance to oxidation, humidity, and mild chemical exposure, making these springs suitable for indoor machinery, light outdoor fixtures, and environments where carbon steel would rust. For highly corrosive or marine environments, 316 stainless steel may be more appropriate.

These springs are designed to fit standard spring pockets sized for 16mm or 17mm OD springs. Always verify your pocket diameter allows a small clearance (typically 0.5–1mm) around the OD for smooth compression without binding. The 1.5mm wire diameter is compatible with most light-to-medium duty spring seats.

304 stainless steel performs well in most outdoor environments with exposure to rain and humidity. However, prolonged exposure to saltwater or strong industrial chemicals may cause surface staining over time. For coastal or highly corrosive outdoor applications, consider a protective coating or upgrade to 316 stainless steel springs.

Measure your spring pocket or guide rod diameter. If you are using a guide rod, the spring's inner diameter (ID = OD minus 2× wire diameter, so approximately 13mm for 16mm OD or 14mm for 17mm OD) should be slightly larger than the rod to slide freely. If you are using a pocket, the OD should be slightly smaller than the pocket bore. Choose the OD that gives you the correct clearance for your setup.

For prototyping or testing, a 1–3 piece pack is ideal to validate fit and function before committing to larger quantities. For small production runs or to keep spares on hand, packs of 10–30 pieces offer better per-unit value. Select your preferred quantity from the QTY(pcs) variant option above.
