We
are pleased to announce to our product line Corremaks fasteners, our long term
partners EJOT now offer self-tapping screws for highly corrosive
environments like swimming pools, underground parking lots and tunnels. This is
possible through the use of austenitic stainless steel (1.4529), which is in
accordance with resistance class IV of Deutsches Institut für Bautechnik
(Z-30.3-6).
Due
to a special production method developed by EJOT, the thread edges of EJOT
Corremaks screws reach a particularly high strength. Thus a process-sure
screw connection in steel substructures up to S320 is possible. Laboratory
tests impressively prove that the edge strength suffices to form the internal
screw thread. The thread edges remain intact, so that a gearing of connection
element and steel beam, which is necessary for a lasting protection, is
guaranteed.
With
the Corremaks screw, EJOT combines the advantages of an economic and
secure installation of thread moulding sealing screws with the requirement of
maximum corrosion protection where it may come to high concentrations of
chlorides, sulphur dioxides or further pollutants. The screw is technically
approved (Z-14.1-4).
