Self-perforating dowel for Alu hangers
Carbon steel with white galvanic zinc coating
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 wood-
aluminium 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
