Conical Countersunk Recess: Features an angled internal bevel that accepts 90° countersunk screw heads, allowing them to sit perfectly flush within the washer body.
-
Broad Bearing Surface: Flat bottom face distributes high clamping loads across a wider surface area to prevent screw heads from pulling through or crushing timber.
-

Versatile Fastener Compatibility: Designed for use with countersunk wood screws, timber fasteners, and machine screws where surface distribution or reinforced clamping force is required.
