The ESCR is a washer head screw designed to connect two or more
timber members together.


  • Service class 2
  • Acier electrozingué jaune
  • Intérieur


Technical approvals : EN-ETA-13/0796
Declarations of Performance : 

Heat Treated Carbon Steel

Finish: Electrogalvanised with Yellow Chromate and anti-friction coating. Zinc coating thickness ≥ 5μm.

Warning: Industry studies show that hardened fasteners can
experience performance problems in wet or corrosive environments.
Accordingly, the ESCR wood screws should only be used in dry, interior and non-corrosive environments e.g. Service class 1 & 2.


The ESCR screw has a reamer to allow for
smooth driving of the shank. The large washer head gives high head pull-through resistance while allowing the timber members to close up firmly.
