Self-perforating dowel for Alu hangers

SPECIAL TIP
The self-perforating tip with bleed shape is specially designed to obtain the fastest possible penetration of wood and aluminium.

DOUBLE THREAD
The thread up against the tip facilitates screwing (Lg1); the increased length of the underhead thread makes for fast, accurate closure (Lg2).

INCREASED DIAMETER
The diameter of 7.5 mm ensures a shear resistance of over 15 % and enables optimisation of the number of fasteners in the joint.

CONCEALED HEAD
The small-diameter concealed cylindrical head ensures an optimal appearance and meets fire-resistance requisites.

FIELDS OF USE
Self-perforating system for woodaluminium concealed joints. Ideal for ALU bracket with screwdrivers with 1200 - 1700 rpm. Service classes 1 and 2.

APPLICATIONS

  • The connectors allow for the rapid and precise execution of retractable junctions on aluminium alloy brackets (AluMINI and AluMIDI brackets). The reduced dimensions allow for excellent fire protection;
  • For applications on reinforced concrete or other uneven surfaces the self-drilling dowels allow a greater installation tolerance when fixing
    the timber element. Values are certified, tested and consolidated.
