ESCR - Structural Wood Screw
The ESCR is a washer head screw designed to connect two or more timber members together. 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.
Material: 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.
ESCR screws install best with a low-speed drill and a T-40 or T50 6-lobe bit (one included per box).
Pre-drilling is typically not required. ESCR screws may be installed through metal truss plates as approved by the truss designer.
Drive the fastener so that the top of the head is slightly embedded into the top surface of the timber. To ensure correct performance, do not under or over-drive the fastener.
Individual screw locations may be adjusted up to 75mm to avoid conflicts with other hardware or to avoid timber defects.
