The inserti threaded they allow to obtain of the reliable and resistant anchorages in presence of materials with thin spessori. It rests can be carried out the "blind person", on accessible pieces from a single side, fastly and without details operations. For velocizzare the operation the use of pneumatic attrezature is advised.

TECHNICAL NORMS: the immense range of the materials and the forms used for the construction of the inserti threaded allows to resolve every inherent problem the assemblage of the ended manufatto one. The three various witness, ROUND, SVASATA and REDUCED concur various and reliable solutions. The materials in steel, aluminum and stainless steel allow a corrected connection to the base structure. Councils to pierce one 0,10 milimeter in more of the external diameter of the file. The hexagonal file concurs an absolute guarantee of possible spins.
