GRK Fasteners R4 #10 x 3-1/8" Bugle Head Screws, T25 Star (Torx®) Drive
GRK Fasteners R4 multi-purpose framing and decking screws are engineered for strength, speed, and reliability in a wide range of construction applications. Designed for general framing, remodeling, decking, and structural assemblies, these screws deliver superior holding power while reducing installation effort. The patented W-Cut™ thread design lowers driving torque, while the T25 Star Drive virtually eliminates cam-out for faster, more efficient installation.
The advanced CEE Thread™ enlarges the pilot hole as the screw is driven, reducing wood splitting and minimizing rework. Climatek™ coating provides enhanced corrosion resistance, making these screws suitable for use in pressure-treated lumber and approved for ground-contact applications.
