A
range of self tapping masonry anchors which tap their own
thread into masonry or concrete. Available with either
a 5/16" standard hexagon washer
head, (which can be washered and colour capped) or a phillips
3 recessed countersunk head. Blue ruspert finish for superior
corrosion resistant which also helps distinguish them from
other standard screws.
Boxed
in 100s with free masonry drill bit, (available with free
SDS hammer drill bit per 250 on larger quantities) are
easily installed with a standard drill, and because there
are no plastic plugs or re-alignment to consider, and the
high consistent pullout values obtained, are an ideal method
of fastening in numerous applications.
Benefits
- Noncombustable
- Fixing
at edge (no bulb of pressure)
- Consistent
high pullout values
- No line
up problems
- Quick
and easy installation

Anchor Choice
Build up + Penetration (minimum 25mm) = fastener length
In hard rock concrete too deep a penetration will cause excessive
torque
Installation
1. Pre-drill 3/16" diameter hole (minimum 6mm deeper than
anchor penetration)
2. Drive Anchor
Typical Applications
Batten/counterbattening to underside concrete floor slab,
window/door frames, wallplates, signs etc.. Brackets for
handrails, ducting, aerials, trunking etc.. In fact anywhere
a fixing to concrete or masonry is required.
Manufactured
from high grade carbon steel and case hardened. Ruspert coated.
The unique thread design
gives exceptionally high holding power in concrete or brick
materials.

For on site pullout testing please contact sales.
Pullout tests can be arranged depending on location and
given suitable notice.
Tests carried out with gauges manufactured to BS EN 837-1
1998
All figures are average test results and are ultimate failure
loads. No safety factor has been used.
Not suitable for light weight block.
