Description
Product Overview
The 304 Stainless Steel Type Torsion Spring from KRUPOVIUS is a precision‑engineered component designed for a wide range of industrial and DIY applications. Constructed from high‑grade 304 stainless steel, each spring offers exceptional corrosion resistance, ensuring long‑term performance even in harsh, moisture‑laden environments. The spring features a wire diameter of 0.8 mm, an outer diameter of 6.3 mm, and a total length of 43 mm, forming four tightly wound coils that provide a 180 degree deflection angle. This geometry enables the spring to store and release energy efficiently, making it ideal for mechanisms that require consistent torque and reliable return motion. The package includes 20 identical springs, giving you ample inventory for replacements, bulk projects, or multiple installations.

Usage
These torsion springs excel in a variety of settings. In the home, they are perfect for retrofitting or repairing garbage storage buckets, where a smooth lid‑closing action is essential. In industrial contexts, they serve as critical components in machinery such as valve actuators, latch mechanisms, and small gear assemblies. Their compact size allows integration into tight spaces, while the 180 degree rotation capability provides sufficient leverage for both light and moderate loads. Whether you are a hobbyist working on a custom tool, a small‑scale manufacturer needing reliable spring action, or a maintenance professional replacing worn parts, these springs deliver consistent performance. Their stainless‑steel construction also makes them suitable for outdoor equipment, marine applications, and any environment where rust resistance is a priority.
