Why does it take two pulls of a tool to install Avdel® fasteners?
If the installation tool is an Avdel® tool, this is often due to neglect in priming the tool with oil. Priming procedures and tool servicing are detailed in the relevant tool manuals. If the tool is not an Avdel® tool, it may be a universal tool which has not been specifically designed to install Avdel® fasteners.
