I just want to say up front THANK YOU to people who generously share their knowledge. I really am very grateful.
The Center cabin brace is attached to the cabin top with four screws (MS24694S72) and four spacers made from aluminum tube (AT6-058X5/16).
Here is the part I am having trouble with, the head of the screw is almost the same diameter as the spacer which is the diameter of the hole.
Screw head Diameter .351
Spacer Diameter .312
Hole diameter 5/16 .312
How does this setup hold the brace securely? Surly, I am completely missing something? Can someone please set me straight?
Thank you! Thank you!
