The self-perforating tip with bleed shape is specially designed to obtain the fastest possible penetration of wood and aluminium.
The thread up against the tip facilitates screwing (Lg1); the increased length of the underhead thread makes for fast, accurate closure (Lg2).
The diameter of 7.5 mm ensures a shear resistance of over 15 % and enables optimisation of the number of fasteners in the joint.
The small-diameter concealed cylindrical head ensures an optimal appearance and meets fire-resistance requisites.
FIELDS OF USE
