ESCR - STRUCTURAL WOOD SCREW The ESCR is a washer head screw designed to connect two or more timber members together.
ETA-13/0796, UK-DoP-e13-0796
FEATURES
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. Benefits 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.
APPLICATIONS Suitable On I-Joists, SIP Panels, Roof Trusses, Timber Frame Panels, Composite Panels, Engineered Timber, Metal Web Joists. When to Use Connection of multi-ply timbers.

a) The thickness of the secondary member is not sufficient according to ETA-13/0796 annex 7 table A6.9, so no values are given for these dimensions in case of wood to wood connection. For Steel to wood connection no minimal thickness is defined.
•
The tension resistance of the thread have been calculated with an angle between 45° and 90° compared with the grain
• • • • • • •
The geometry and mechanical properties are defined in ETA-13/0769. The values are for a timber class C24 # = 350 kg/m³. The thickness of the secondary member (AD) has been chosen equal to the length of the smooth part. All values have been calculated with a thread totally drown in the primary member. For connection steel to timber, the thickness of the steel plate is equal to the diameter for calculation. Subject to setting and printing error The values given are available to help the design. Projects must be carried out exclusively by duly licensed professionals.
