GRK Fasteners is a privately held company that manufactures its own patented, high quality, specialty fasteners for distribution across the planet.
GRK Fasteners are the ORIGINAL star-head screws, and most combine some or all of the following features: self-tapping (to reduce or eliminate the need for pre-drilling),
W-cutTM thread design, cutting pockets under the head (to reduce or eliminate counter-sinking), sharp threads, zip-tip,
built-in washer head, reverse threads, exceptional strength and flexibility, resistance to corrosion, and other innovative features !
