What should a bolt anchor be like to ensure safety effectiveness?

A bolt anchor needs to be tight and free from corrosion to ensure safety effectiveness. A secure fit means that the anchor can handle the loads and forces applied during a rescue or climbing operation without the risk of disengaging or failing. Corrosion can significantly weaken the integrity of the anchor material, which can lead to unexpected failure under load. Therefore, it is essential that the anchor is not only tight to provide necessary support but also maintained in a condition that keeps it free of rust or other degrading factors. This ensures that the anchor can be relied upon in critical situations, enhancing safety for all involved.
