Re: pedestal mount bolts?
Scott,
I used these Toggler toggle bolts
http://www.westmarine.com/webapp/wc...001&storeId=11151&partNumber=543785&langId=-1
Here is how they work:
Drill a 1/2" hole. Insert the toogle bolt and while appling upward pressure slide down the retaining collar to the surface. It is sort of like a zip tie in that it keeps the toggle portion firmly in place under the deck.
Then you simply snap off the remaining piece leaving just the collar holding the toggle plate. Very neat and easy.
You can then fill these holes with sealant right before you insert the screws so that everything is protected from water.
Simple and strong. They sell a non-stainless version of this in Home Desprate and such.
These go under the deck and use a 1/4"-20 SS machine screw or bolt from the top.
