Structural Washer Head Wood Screw
ESCR is a washer head structural screw designed for load-bearing timber structures. The ESCR screw has a milling thread 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.
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.
