Finding replacement grub screw size for EFP arm hinge rods
What the thread found
- The grub screws that secure the rods on the hinge connecting the two arm sections can be stripped and need replacement
- A metric-sized grub screw is suitable for this application
- The issue can be resolved by re-tapping and using a metric screw
Depends on
- The original screw size specification was not confirmed in the discussion
- Solution involved re-tapping rather than finding an exact original replacement
