GRK Fasteners R4 Multipurpose Screw #8 x 2-1/2" Handy Pack (100 Count)

The GRK R4 Multi-Purpose Screw is engineered to deliver fast, reliable fastening in a variety of materials—from wood framing and composite decking to cement fiberboard and treated lumber. Each #8 x 2-1/2" screw features GRK’s patented Climatek™ coating for superior corrosion resistance in both interior and exterior applications where moisture exposure is intermittent and code approval is required for treated lumber.

Boasting a Zip-Tip drilling point and six self-contained cutting pockets, the R4 installs without pre-drilling and minimizes torque for rapid one-step fastening. Its bugle head neatly countersinks below the surface, while the Star Drive recess virtually eliminates cam-out, ensuring a clean finish every time.
