SELF-DRILLING DOWEL

SBD

SBD is the self-drilling system for hidden timber-steel and timber-aluminium joints.

The concealed cylindrical head ensures optimal appearance and fire protection.

Certified, tested and calculated also for fastening standard Rothoblaas plates such as the TYP X or F70 pillar-holders.

Discover the effectiveness of SBD, the self-drilling dowel for concealed timber-metal joints.

The SBD dowel is ideal for joining head beams and making continuous beams, restoring shear forces and momentum.

The special self-perforating timber-metal tip geometry reduces the possibility of breakage in the screwing stage.

The diameter of 7,5 mm ensures a shear resistance of over 15 % and enables optimisation of the number of fasteners.

The thread up against the tip facilitates screwing; the increased length of the under-head thread makes for fast, accurate joint closure.

The small dowel diameter guarantees joints that offer high stiffness. It can be used with screw guns running at 600-1500 rpm.

In carbon steel with bright zinc plated, it can be used on steel and aluminium. Service classes 1 and 2.
