Did you know that even solar panels require loosening prevention measures for their fasteners?

Where HARDLOCK® nut prevents accidents:

  1. Solar panels mounted vertically
  2. Solar panels mounted on roofs (schools, public buildings etc… )
  3. Areas with strong winds and strong temperature differences (micro-vibrations)
  4. Areas with large differences in overnight temperature and daytime temperatures (loosening due to thermal expansion)
    Many companies use pal nuts (DIN 7967) to try to prevent nuts from coming off the bolt. However pal nuts unfortunately are one of the least reliable loosening prevention measures. But great because they are cheap…
