ESCR
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.

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 ρ = 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.
