METRIC HELICAL SPRING LOCK WASHERS
- Add strength and insure against equipment breakdown; non-linking, positive locking.
- For use with 12.9, 10.9 and 8.8 fasteners.
- Compared to regular flat washers, split lock (or spring lock) washers reduce the likelihood that your fastened joint will loosen under shock or vibration. Under compression, spring tension forces the split ends to dig into mating surfaces and hold tight.
