ASSY 3.0 A2
®

Application:
The ASSY 3.0 A2 of corrosion-resistant,
®
austenitic stainless steel is designed especially
for applications outdoors, in damp rooms and in
salty atmospheres.

Tip:
Ring thread → Minimal splitting effect, especially
when screwing in near the edge

Thread:
Countersunk head* Asymmetrical coarse thread for short screw-in

N = Lowest corrosion loading within the respective environment, + = Probably the best choice of materials with regard to corrosion
characterized, forexample, by low temperatures and low humidity resistance and costs
M = Medium corrosion loading within the respective environment (+) = Sufficient behaviour, provided certain precautionary measures are
H = Higher corrosion loading within the respective environment, e.g. due taken. Smooth surface finishes and regular cleaning are especially
to continuously high humidity, high ambient temperatures, especially important
aggressive air pollution – = Probably heavy corrosion
x = Basically meets the requirements, however less expensive steels could
also be sufficient
AUS. pub. 06/15 © ASSY 3.0 particle board screws are optimized for use in wooden materials. When used in plastic

®
anchors, a reduction of the load-bearing capacity is possible. For this reason, we recommend only using
screws without optimized thread tips.
