A sample of applications for Castle screw pockets
Pilot Hole: The pilot hole is drilled from the edge of the material creating a communicating hole from the pocket clear through to the edge of the material.
Low 6° Angle: The low 6 degree angle reduces shifting forces that can result in uneven joints.
Web: The web easily adjusts from 5/8″ to 7/8″ to suit a variety of screw lengths from 1-1/4″ to 1 5/8″.
Pocket: The routed pocket leaves a clean slot without tear out typical of drilled pockets.
