SPAX yleisruuvi R 88093 Ruko-kärki/T-STAR plus 4,5x25/22-T20 sinkitty WIROX 1000 kpl (0201010450255)

Driving screws into wood, chipboard, MDF, plastics, and thin metal sheets often means pre-drilling, struggling with countersinking, or dealing with stripped recesses. This SPAX universal screw eliminates those steps: the 4CUT point reduces splitting and removes the need for pre-drilling in most wood types, while the multi-head design countersinks flush without a separate bit. The T-STAR plus drive provides a secure fit for T20 bits, reducing cam-out during installation.

Who is it for

Professional carpenters, joiners, and serious DIYers who need a reliable, all-purpose screw for interior and exterior wood applications. The galvanized WIROX coating offers corrosion resistance suitable for outdoor use, making this screw a versatile choice for construction and renovation projects.

Tips

Use a T20 T-STAR plus bit for optimal drive performance. For hardwoods or dense materials, a pilot hole may still be recommended despite the 4CUT point. The WIROX coating is suitable for outdoor use; for highly corrosive environments, consider stainless steel variants.
