With the screws torqued down, there will be little of no relative movement between the lanyard and the screw threads.Be sure to check those anchors periodically; I would be concerned in the long term that the threads of the screw will wear away or fray the cable material on the anchors. It's not pretty, but it works!![]()
The solution offered by @pchaps looks good, too.
Has anyone found eye bolts with a M4 0.7mm thread?
