Simply put, GRK screws are some of the toughest screws around. These aren’t one and done screws. Use them time and time again without fear of the head breaking off. Using general construction screws, drywall screws, or any non-structural screw can be dangerous when installing climbing products.
GRK #9 and #10 screws are so good that they’re literally the only screw we recommend for installing climbing holds and training tools.
