R4™ Multi Purpose Screw

R4™ Multi Purpose Screws offer a self-countersinking screw, into even the hardest woods. Cutting pockets under the head transport drill dust away while cutting a perfectly clean screw hole, whilst the screw head closes the hole off with precision, leaving no damaged fibres around the head.

R4™ Multi Purpose Screws are recommended as deck screws, providing a versatile timber fixing, along with composite materials.

GRK Fasteners are known world-wide as the industry's toughest screw, with a variety of innovative features to create the perfect, fast and simple to use timber screw available.
