Hexagonal head screw with assembled washer
Self-drilling hexagonal head screw.
In one same step it drills and threads. It offers a visible reduction in assembly times and a greater mechanical resistance comparing to other fixing methods. During its productive process it receives a thermal carbonized, hardened and tempered treatment. The anticorrosive treatment is performed by means of a galvanized electrolytic dehydrogenation, therefore obtaining its silver effect. Its presentation is assembled with metal/EPDM moulded-on washers that are necessary for waterproofing. They are used for joining metal pieces thicker than 1mm, in steel framing or wood framing construction, big metallic structures or industrial structures such as buildings, as well as in bodywork, etc. They come in boxes and the quantity depends on the screw measure.
