INSTALLATION TIPS
Minimum screw anchorage depth:
for dense building materials -
30 mm,
for aerated concrete and
timber - 60 mm.
FEATURES
1. No expansion force therefore
imposes less stress on substrate
during installation.
2. Small hole diameter giving high
loads.
3. Easily removed for temporary
works.
