[quote=Dogboy]Actually, a spacer will help with the loading of the bolt because it will allow the flange of the strap and the head of the bolt to bear against a solid surface, so lateral load will be transferred to the flange of the bolt, through the spacer, and to the deck. The spacer would give the bolt and strap something solid to bear against which will improve the overall strength of the attachment. It will be a safer and more robust setup all around.
