Questions and Answers for Tommy Docks 8 in. Long Gray Polyester Powder Coated Cast Steel Auger Foot for Dock Post Pipes in Boat Dock Systems, 2-Pack

A:  1-5/8"

A:  We do not stock augers for that diameter of pipe.

A:  No, PVC is not recommended.

A:  If your dock is attached firmly at shore, it is unlikely you will require augers, unless the lake bottom is soft/muck.

A:  I was worried about the instability of the river bottom because it shifts around with the current. My installation is year round. the top of that part of the river can freeze in winter and didn't want to risk movement due to ice. Not sure of your conditions.

A:  Get the augers if going into sand or muck

A:  I use the augers to sink my poles about 3 feet in to the river bed and find that my dock is very stable. I use the augers mostly for easy insertion and removal. My river has a very strong current and the feet allow would not hold my dock. I do not have any experience in a lake situation were foot pads alone my be enough.

A:  as deep as you can

A:  I drive my about 3 feet into the river bed and find my dock is very stable. The current in my river is very fast and there is a lot of debris that floats into the dock and the poles have always held.

A:  I really depends on the lake bottom condition. If the lake bottom is very soft, you will want to auger until you reach material that will allow the auger to do what it is supposed to do. So, there is no real set depth.

A:  I review several recommendations and ended up putting 2 feet of pipe below ground. We installed in our pond which has a mud/clay bottom. The soil in our area is Indiana clay, therefore it's pretty solid when you get a couple feet down. So 2' + 8" (the length of the auger). Dock has been in for over a year and is heavily used... it's still as solid as the day we installed.

A:  The bolt is a 3/8" dia stainless steel hex bolt.

A:  7/16 included

A:  There is a stainless steel bolt that tightens on the end of the pipe, please make sure you have the auger fully tightened prior to trying to auger into the ground.

A:  With included bolt

A:  1.66inch (Outside Diameter)

A:  My pipe has a 1.5" ID with a 1.9" OD. I returned this product because this auger has too small of an ID for my pipe so I'm guessing it is for the next size smaller pipe.
