Use threadlock on the bolts to stop them vibrating loose.
I dont see any problem supporting the router with those bolts. If they were used to hold a bracket to the ceiling you could easily swing on them all day without them breaking.
What make of router did you buy?
Not sure I'd want to swing my bulk on four M4 screws on a bracket on the ceiling
The router is an own brand router from a DIY/building company this side of the pond called Wickes - https://www.wickes.co.uk/Wickes-Mult...500W/p/150411#
Hi Jon, I am with Bob on that one. No point drilling more holes - if you are really worried, use longer bolts and lock with nylock nuts under the router base. You could even use high-tensile bolts, if you could find that size, but overkill.

Bob's idea of using a thread compound would help if the threads are worn but use the type that is just to keep them from vibrating loose and not the actual thread locking type. In Loctite brand it would be the blue colored one.
It's not so much the screws themselves I'm concerned about as the threads in the router plate which are not great to begin with (I had to tap them properly to even take the M4 screws, the plastic plate that was on the router had been fitted with Taptite screws
) and are in a relatively thin section cast aluminium. I don't really want to drill right the way through just yet as that will totally invalidate the warranty for the router although that is always an option in the future. I'd definitely going to be using some form of thread lock whatever I do.
I must admit, coming from an engineering background I'm surprised that, given the forces involved, this is considered acceptable to hang a router on but I know very little about routers so I'm always open to advice from those more experienced than me. I'll leave it as it is for now and just monitor it carefully. If it looks like things are loosening up, I can always beef it up later.
