Blue Wall plugs
For screw sizes M6 and above
Drill hole 10mm
Blue wall plugs are for very heavy duty applications.
They are big enough to take M6, M7 & M8 screws.
If you find that the wall you are drilling is extremely hard
(some types of concrete and most lintels)
Start by drilling a smaller diameter hole (eg 4mm).
The smaller drill will penetrate the wall more easily than a large drill
as the hammer impact is concentrated on a much smaller area.
Then drill out with a 7mm bit and finally the full 10mm.
Manufactured using virgin material to ensure perfect quality
with tremendous holding and binding qualities giving less likelihood
of hole spin.
Using first rate polymer enables the plugs to be used in
extreme temperatures without splitting or cracking.
