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.
