would be a good choice for such an operation where the surrounding material is also aluminum because of its good blending and polishing characteristics material choices can thus be decided on an individual basis depending on specific application needs the preferred embodiment in fig1 to 3 depicted shows an inward bevel on the back surface 4 of the screw head as depicted the bevel describes an angle of 82 degrees this is a commonly available standard bevel angle for flat head machine screws and is intended to mate with a similarly angled bevel in a countersunk hole in the material to be fastened any current or future available standard or custom bevel angle is permissible other angles commonly found are 90 degrees and 60 degrees for example the top or front surface 2 of the screw head in the preferred embodiment as depicted in fig2 is flat and unornamented as such it can function unaltered or it can be used as a base for further treatment examples of further treatment include but are not limited to being textured printed etched anodized punched embossed stenciled painted ground or polished the tail or insertion end of the screw in the preferred embodiment as depicted in fig3 features a hexagonal socket 3 for a torqueable drive access because the hexagonal style of socket drive is the most commonly used style in set screws and because the driving end of a set screw is analogous to the insertion end of my invention it provides a convenient standard for use in the preferred embodiment of my invention furthermore it ensures that existing technology can be readily adapted to manufacture the screws and that standard.
