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.

Installation:

• 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.
