The bolt that has made us famous in Italy first and then in the World.
Type of bolt with a compact cylindrical head and hexagon socket, may be combined with a shank formed by a helical spiral which works by distributing loads on the shank itself, thus increasing elasticity.
Easy to drive thanks to the good grip offered by its specific key, ensures improved and easier assembly.
Its peculiarity is to be able to transmit considerable torque, higher than bolts with a flat blade or Phillips driver, occupying less space. Primarily used in assemblies where compactness and tightening precision are required.
