What requirement must tiedown assemblies and fastening devices meet regarding knots?

Tiedown assemblies and fastening devices must not contain knots to ensure safety and reliability during use. The reason for this requirement is that knots can weaken the overall strength of the tiedown assembly and may slip or come undone under pressure or movement, which can lead to the load becoming unsecured. By avoiding the use of knots, tiedown systems can maintain their intended load capacity and structural integrity. This enhances safety during transportation and prevents accidents related to load shifting or failure.

Additionally, regulations and industry standards typically specify the use of hardware and fasteners that provide a dependable connection without the potential weaknesses introduced by knots. Such practices contribute to better performance and compliance with safety protocols.
