Window Concrete Frame Screws have an undercut head design and a torx drive recess for positive installation performance. They are ideal for securing metal fixtures to hard surfaces by pulling flat against the surface.
The masonry torx screw offers quick and effective light duty anchoring solution for fixing into multiple materials such as concrete, brick, stone, concrete block and wood. The hi-lo thread configuration taps its own thread within a pre-drilled hole in the substrate material allowing for adjustment and accurate installation.
