FASTAP LAMINA SCREWS are zinc plated and specifically designed to assemble melamine. The patented Power Point 2 tip design drills the pilot hole as you install the screw. NO pre-drilling! The exclusive self-countersinking flat head with nibs carefully locks the screw in without chipping or cracking the melamine surface. The special coarse threads fully grip and hold throughout the full range of particleboard densities used with melamine.
