Background:
A ring was found on a RADIALIS PRO harness in a high ropes course with the thread broken off just behind the nut. In a metallurgical assessment of the bolts, it was found that there were variations in the coating of the bolts, which can lead to hydrogen embrittlement and the bolts snapping in individual cases.
