![]() A 4 1/2" screw to hold 2X together? A bury of 2" works pretty good in most cases, in a joint that does not have much stress applied to it. The part about end grain not holding a screw well is true, but I find the screw does not need to be that long at all. ![]() When fastening a piece to the end of another, as in making a corner for a box, I heard a long time ago the screws needed to be 3 times longer than the piece you are fastening, because end grain does not hold a screw as well as going into the wood perpendicular to the grain. When screwing into oak or other hardwoods, 3/4" will hold very well. I have also seen 3/4" or less, work well in thin material that you may not want to go all the way through, but there may be need for many screws needed in a given area to have a strong hold. On deck boards, IMHO, 3" screws for a 5/4 deck board is way over kill, 2 1/2" is plenty for that. Of course, there are variations on this, depending on the circumstances. When fastening wood, once the piece to be fastened is gone through, generally I find 1" into the second, or the piece you are fastening to is enough to hold. Wedge fasteners may be a better choice for that, or better still an anchor bolt with expansive concrete set into a drilled, cleaned hole will hold the most reliable if strength and resistance to vibration is what you are looking for. That can be as simple as the judgment call of "this thing is really heavy and I don't want it to move so I will use the bigger diameter one" or, "This will not be too tough to set, so the small one will do." If the item you are going to secure is going to vibrate, I strongly advise against using concrete screws, unless glue can be used in some way to help keep it together. ![]() There are 2 different diameters to chose from too. If you are setting it in the joints of the brick or perhaps cinder block or a soft brick like older handmade brick that are not real dark, 1 3/4" into the material is pretty easy to do. In my experience, in hard concrete, or brick, a screw will break after 1 1/4" into a hard surface. I checked the website and it is mentioned that the depth can be as deep as 1 3/4" bury into masonry. The screws are sold at those lengths with that in mind. On Tapcons, Philcons or Con-certs or just good old concrete screws, 1" embedment into is the typical depth I see referred to. You can help Capcom Database by expanding it.I will to try to give a few numbers you may find useful based on what I have found over my years of connecting one thing together or the other. Leo returns to the island as a hero, but his adventures as a diver may just be starting. Leo eventually ventures to the sunken submarine to recover the Erebos and is successful in returning it to Telospolis, calming the oceans. At this point the ocean begins to turn stormy as the power of Erebos runs out of control. The search is cut short when it is discovered that SeaDross has discovered Erebos in Telospolis, however, they failed to realize the malevolent powers contained within the relic causing their submarine (and Erebos) to sink to the ocean depths. Leo and his friends race against time to locate the Erebos, diving to several underwater locations including: a sunken Ferry, a crashed 747, an old cruise ship, a pirate Galleon and an ancient underwater city called Telospolis. While on the island, Leo and the Amigos discover that a nefarious aquatic salvaging company named SeaDross is searching for an ancient pirate treasure called Erebos. There, they meet a group of scuba divers called The Amigos. Their ship sinks in a huge storm and they swim to a nearby island. Leo is a diver who sails through a fictional treacherous Caribbean sea with his friends. ![]() Over time the player unlocks dive sites such as a sunken freighter, a downed airplane, a pirate ship, a sunken luxury liner, a submarine and an undersea temple. This money can be used to buy equipment allowing a player access to deeper and more challenging dives. As Leo, the game's only playable character, the player earns money by finding precious materials with their metal, glass, wood, clay, and stone sonars, and looting artifacts from shipwrecks.
