American Screw Fasteners

American Screw is a term that refers to either a standard kitchen or bathroom wall appliance, or to an individual piece of the device."american screw & barrel" The appliance itself is generally a masonry block with interlocking design and a metal cover (the "body") held securely in position by felt rings and other means. These blocks are known as clamps (for cement blocks) or screws (for metal screws). Whatever their name, they all work by applying a compression force between two surfaces, or between two pieces of metal.

In masonry, this force is harnessed and directed through an intermediate contact point (contact mark) on the wall."american screw & barrel" "american screw & barrel" This contacts are generally made of steel or aluminum; but materials may include brass, bronze, nickel, chrome, gold, and others. To apply the screw, one must apply a driving force through the contacts, which results in a compression of the material. Once the screw is totally embedded in the surface of the wall, a series of grooves may be present to channel the material into the next channel. At this point, the screw is fastened in place.

In bathroom fixtures, this type of screw can be adapted for such things as towel rods, shower curtains, or vanity lighting."american screw & barrel" "american screw & barrel" However, since its original application, the most common application is in kitchen or bathroom walls. American screws of this type are usually constructed from high-carbon steel or copper, and may be decorated or covered with brass or chrome. Some decorative examples include those cut in the shape of lanterns, or shaped like birds or flower petals. These decorative screws may be free-standing or mounted to a wall mount faucet or to a vanity counter. They may even be incorporated into a finished interior design theme, or even into the floor covering of the room or area in question.

Installing an American screw can be difficult, because these devices are larger than most hand tools, and therefore require a bit more advance preparation."american screw & barrel" "american screw & barrel" In order to install this type of tool, you need to locate the channel of the screws that will be installed. Once located, it is important to set the screw pressurizing mechanism in the "working" position, so that it can be turned slowly while simultaneously holding the masonry block or tube in place. The reason for this is that the pressurizing mechanism must be able to turn the screw at a rate that prevents it from being damaged. If the pressure is too high, the masonry block may break, or the screw could be damaged.

Alternatively, if the screws are installed to a piece of wood or metal, they need to be turned using a drill press, or by hand with a long screwdriver."american screw & barrel" "american screw & barrel" This pressurization requirement makes these screws particularly useful for installing large pieces of metal, such as refrigerator coils. Since the screws may be very long, they have the potential to become blunt from vibration during operation. Therefore, manufacturers recommend not using a hammer when pressing the screws. In addition, some screws may have a certain amount of lead which needs to be leached out prior to installation.

Screw fastening hardware is typically sold in either a box or CD form."american screw & barrel" Many times, it is easier to locate screws in this format, as the screws will be identified according to their specific slot location. When fastening screws into masonry, it is important to have a level; this ensures that the screws will be properly seated and that they do not slip out of their slots. Typically, there is a small metal tab or lever that adjusts the tension of the screws, so that they do not slip. However, because the screws are installed in a metal sleeve, this tension mechanism may be ineffective. If you choose this method of fastening, make sure that you do not exceed the tightening tolerance on the screws.
