Screws For Aluminum Boat Floor

Our pontoon deck screws are designed to be spaced 16 apart and run down through your plywood and aluminum cross members.

Screws for aluminum boat floor.

Your plywood decking sits on top of these cross members and creates the floor for your boat. At fisheries supply we stock a wide variety of specialty fasteners including blind rivets in stainless steel and aluminum threaded rod set screws ring shank nails brass key stock and much more. An example of this is where stainless steel screws and blind rivets are used to install hardware on to the aluminum spars of a sailboat. Using tef gel and other preparations will not completely eliminate the problem.

But sheet metal screws should never be used to fasten hardware to extruded aluminum spars masts booms spinnaker poles and so on because sheet metal screws are designed to be held in place by a single thread and are not meant to cut threads they distort the walls of the hole into a helix. In stock and ready to ship. If you re looking for specialty fasteners or marine rivets you ve come to the right place. As is the case with carbon steel screws a plated stainless steel screw is less likely to corrode aluminum.

All pontoon boats use aluminum cross members or stringers to connect the tubes of the pontoon. When dissimilar metals make contact damage due to galvanic corrosion can occur. Screws treated with a high quality coating consisting of zinc and aluminum flakes are especially resistant to corrosion.
