How long should my fasteners be?

Bolt length measured from the bottom side of the head (flat side) and is related to cabin side thickness plus the thickness of the main frame. For example, if your cabin thickness is 1 inch, the fastener would be 1 inch plus the port window frame thickness (0.200 inch), so you cut the bolt to 1.200~1.300 inches (not below 1.200 inches). Three threads will give you 100% of the working load of the fastener.
