GRK's R4 self-countering screw has a new underhead with saw-blade like cutting teeth and six self-contained cutting pockets. Together they act similar to a circular saw blade, transporting the drill dust away from the edge of the screw hole while cutting a perfectly clean hole into even the most brittle materials without cracking any surface treatment. This design also further enhances the R4 versatility by allowing the fastener to be installed without countersinking into even the hardest woods. The R4 screw closes the hole off with precision, leaving no damaged fibers around the head. Applications include wood, particle board, plastic, sheet metal, cement fiberboard, composite decking, wood decking and melamine.

Reinforced neck for increased driving torque. Bugle head for self countersinking. Square drive for no-slip cling fit. Coarse threads for extra holding power and faster uniform draw-down. Extra Sharp point easily penetrates wood without pre-drilling. Sawtooth threads for faster driving of screws without splitting.

For use in all particle board materials. Particle Board is made from adhesive-bonded chips of wood. Only flooring grade particle board which is compressed to a higher density than the standard material, should be used for sub floors.
