What type of nuts should be used to prevent loosening of anchorage bolts on a cantilevered scaffold?

Lock nuts are specifically designed to prevent loosening due to vibration or movement, making them an ideal choice for anchorage bolts on a cantilevered scaffold. They achieve this by incorporating a nylon insert or a deformed thread that creates additional friction against the bolt, ensuring a tighter grip. This is crucial in scaffolding applications, where stability and safety are paramount; the risk of bolts loosening can compromise the entire structure.

While standard nuts, hex nuts, and wing nuts can serve various fastening purposes, they do not provide the same level of resistance to loosening as lock nuts. Standard and hex nuts may relax over time under dynamic loads, while wing nuts are typically used for tools requiring frequent adjustments rather than secure, permanent fastening. Therefore, lock nuts are the most suitable choice for ensuring the integrity of anchorage in scaffolding.
