• WIROX (on R) is SPAX's original coating and exhibits excellent corrosion resistance.
• Chamfering is also done with the screw head part, and it can be screwed beautifully.
• By driving with an electric drill, scratches on the screw surface are suppressed and rust generation is reduced.
• There is no need to drill a bottom hole.
• For hardwood, rafters and wood decks.
• Use a drill driver. (Rust-proof coating may come off.).
•  
• You can also use commercially available Torx bits, but you can work more easily with T-STAR plus special bits.
