Stripped hub adapters bolts

The grub screw that holds the hex in place sheered off, causing the wheel to comically roll away after landing a jump.


I then stripped the head of the bolt that holds the cap in place. Too much locktite on that one.


What sizes are the grub and cap bolts so I can find replacements? Even better, are there any harder grub screws I can use.


Thanks

For 7075 adapters:

Grub screws for hex = 5x5 mm. I buy stainless cerated from MCMaster Carr.

The tips are cerated to provide more grab.

Hub cap screws = 3x19mm 16mm thread + 3mm head length. Stainless also.

Use tiny drop of thread or you will never

get them loose.

Stainless steel grub screws will be weaker than the steel ones. I use the steel with the cupped tip on my adapters.
