Suitable system
for timber-frame
construction joints
The KonstruX fully threaded screw from ScrewPro is a single
system ideal for all timber-frame construction joints. The
screws can be used for timber engineering and carpentry,
timber-frame construction, hall construction and
construction of timber elements among others.
The KonstruX fully threaded screws maximise a joint’s
load-bearing capacity with a high thread extraction
resistance in both components. If partially threaded screws
are used, the joint’s load-bearing capacity is limited by the
considerably lower head pull-through resistance in the
attached part.
The required edge and centre distances can be minimised
for screws that are only exposed to tension. Doubling up of
joists, for example, increases the load-bearing capacity of
floor joists and reduces bending. Here, KonstruX fully
threaded screws join the components together in a
displacement-resistant manner.

Firm wood
connector
The Alumidi is a concealed beam hanger
from Rothoblaas. The hanger is available
with or without holes. The hanger is suitable
timber-to-timber shear connections, both
perpendicular and inclined to the vertical
plane.
It can be used for various types of timber
including solid timber, glued laminated
timber, cross-laminated timber and wood-
based panels. In addition, optimal hole
spacings are ideal for both timber (nails or
screws) and concrete (chemical or screwed
anchor).
Versions without holes are available in
2 200mm long pieces with notches every
40mm. These can be cut on site according to
the worksite requirements.
