What is the walnut?

Barrel matrix is ​​a female fastening element used to screw the individual pieces of the assembly together without having an exposed nut on one of the facial faces. The hungry matrix consists of a short, straight length of the round rod with a perpendicular, threaded opening through its center. For the installation of the matrix, a hole is drilled, usually from a hidden surface, a working piece in which the matrix fits. Then another hole is drilled into the workpiece to match the position of the math opening. This allows the second working piece to be bolted to the first without any matrix visible on his faces, a useful function in aesthetically sensitive applications such as furniture production. However, uncovered nuts and screw heads tend to spoil the elegant lines of certain items designed for aesthetics and functional attraction. He does not have to look at the steam locomotive, but he certainly lends a design lounger, clearly sticky air. This does not necessarily mean that in the production of a chair on the market or any otherA piece, which could benefit from their own power. The solution is to use the matrix mainly instead of conventional types, thereby avoiding the hordes of ugly, utilitarian fasteners dotted with glossy walnut.

These fasteners consist of a simple length of a round rod with a perpendicular hole drilled through their centers. This hole is threaded by a standard pitch fiber to facilitate the joint. The installation is achieved by drilling the hole to the level of the intended joint into one of the two pieces that connect, usually from the face that will be hidden later. The second hole is then drilled to match the opening through the barrel. The second work part can then be screwed to the first help of a hidden matrix.

6 The use of the barrel matrix rather than conventional types is particularly useful in the production of furniture, where elegant and decorative finishes are essential. Some barrel nuts can be cutBin of the screwdriver at their one end so that they can be turned in tight holes to match the threaded holes to the hole in the hole. In some cases, they can even be equipped with a second or third threaded opening at their ends, which run parallel to the nut to attach other hidden screws.
