Abstract
A self-piercing clamping device, comprising a head, a rod including an externally threaded portion adjacent to the head and a piercing tip at the end of the stem remote from the head, said piercing tip including a pair of diametrically grooves opposite, inclined in opposite directions, and forming acute angles equal to the axis of the rod, characterized in that each of the grooves is defined by two walls that are cut according to an angle substantially greater than 90º and substantially less than 180º and because the grooves are straight and closely approximate one another through the stem at a crossing point, the piercing point also having a pair of flat faces at its free end, these faces being arranged in opposition to the axis of the nose. Shank and triangularly inclined with respect to it, mutually intersecting said faces according to an intersection line that that passes through the geometrical axis and arranged in or immediately adjacent to the crossing point, the line of intersection being also slightly spaced in angular direction, as measured around the axis of the rod, in front of the cutting edge of each groove, what the slope of the associated face that separates from the line of intersection, proportional an angle of clearance of lip behind the cutting edge of each groove.
