I have lost the original screws, so I don't even know what sort of head the screws should have.
My questions are:
1. what size screws should be fitted? Maybe my lashing points are not original.
2. What sort of head should the screws have? Countersunk or round head?

Hi Eric,
Just getting back to the original questions:
See attached photo.
The cleat does have substantially larger holes than the screws passing through them. Below the cleat are the two different size heads on 1/4 UNC/Whitworth screws. As can be seen the newer screw has a smaller head than the WW2 floor screw on the left. Having said that, upon checking my spare cleat the newer type screw will hold the cleat quite adequately even though the diameter at the top of it is smaller than the older type screw.
These cleats are invariably broken when found on the trucks. I think they were just standard hardware items of the day as used to secure awnings on buildings etc.
Cheers,
Jacques
