Evolution Woodmaster Super Cutter Screw 4.0 x 20mm PZ2 Yellow

Screw 4.0 x 20mm PZ2 Box 200 - Yellow Passivated

Double countersunk head which Improves neck strength reducing head shearing in high torque applications.
Countersinking nibs which enables smooth self-countersinking in both timber and sheet material applications
The nibs cut the wood surface, trimming from the edge of the drilled hole.
he screw is driven home flush to the wood surface every time.
Reamer shank this helically fluted milling thread clears drilling debris and reduces driving torque (from 60mm onwards).
High quality aggressive threadform Improves penetration and reduces driving torque.
Deep precision formed pozi recess allows greater torque to be applied and decreases the likelihood of "camming out".
No pre-drilling required in most hardwoods (Particularly dense woods may need pilot hole).
Eliminates splitting even when close to the edge of the timber.
Special long sharp point fluted to capture chips.
