BiROX ® concrete frame screw »BR«
nylon anchor-free direct fastening in concrete or brickwork.
Steel, case hardened, bright galvanized, yellow chromatized,
milling countersunk head and BiROX ® drive no. 30
This screw rationalizes and simplifies the mounting of frames. Window and
door frames of wood, PVC and other materials can be tension free fastened
without nylon anchors.
The thread cuts an interlocking forming thread into the anchoring base. These
expansion-free anchors allow short rim and axial distances. The frames should
be provided with pre-drilled holes of 6,2 mm Ø by the manufacturer. After
installing and adjusting the frames, core holes Ø 6 mm are hammer drilled into
the anchoring base. Drive in the concrete screw and finished. Remove wedges
and aiding devices. (Low density materials, cavity blocks and honeycomb
bricks to be drilled only in drilling mode). The screw head can be countersunk if
needed.
Advantages/cost effectiveness
• tension free frame mounting
• expansion-free anchoring allows short rim distances
• high load capacity due to interlocking thread forming into the anchoring base
