Has anyone tried countersunk Nylon screws, washers and nuts?
Certainly no corrosion issue but are they strong enough?
When that job gets to the top of the list I might give them a try, unless someone has tried them before and knows they are not suitable and why.
I was thinking along the same lines..
these people are possibly the best source of such fasteners:
Skiffy The fibre reinforced nylon screws and nuts are remarkably tough and will never corrode!
For the intended application, with multiple screws, they will be more than strong enough. Another plus is that once fitted the surplus bolt length can be clipped off using garden pruning cutters....
Actually there are many applications on the Mog where replacing steel nuts and bolts with plastic would help, the indicator and tail light fixings come to mind. I feel a project comming on....
