Questions about this product
- How many springs come in this set and what sizes?
- You get five extension springs, each a different wire diameter: 0.6, 0.7, 0.8, 1.0, and 1.2mm. Lengths run from 20mm up to 50mm unloaded. That assortment covers a range of light-duty tension jobs.
- What are these little extension springs good for?
- They pull parts back into place, hold tension, or counterbalance light loads in small mechanisms. People use them to repair toys, small appliances, and latches, or for prototyping. The full-loop hook ends make them easy to attach.
- How far can I stretch these springs and how long do they last?
- Maximum extension is 150 to 200% of the spring's free length, so don't pull past that. Rated fatigue life is at least 100,000 cycles. They work from -40C up to 120C, which suits most indoor mechanisms.
