Resilient outdoor fastening by Spax
- Maximum power transfer efficiency: The T-STAR plus T20 recess gives you a secure bit fit to prevent cam-outs during fast driving.
- Reliable protection against corrosion: Formed from A2 stainless steel, it keeps your exterior wood structures firmly protected from weather and moisture.
- Clean flush surface finish: The countersunk multi head neatly recesses itself into the wood, ensuring you achieve a flat, splinter-free surface.
With the Spax chipboard screw 4 x 20 mm, you can fasten wooden components and hardware quickly, securely, and with total precision. The t-star plus T20 recess provides an optimal bit fit to prevent cam-outs and ensure efficient power transfer. Thanks to the countersunk multi-head design, the screw sinks cleanly and flush into the wood surface without the need for prior countersinking. Its full-thread construction delivers exceptional pull-out resistance and holding strength in thin materials. Made from durable A2 stainless steel, this screw provides reliable protection against corrosion and moisture, making it ideal for damp indoor rooms or sheltered outdoor projects.
Product description:

Application:
- Outdoor applications - Direct exposure to elements
Advantage:
- In the long term, galvanised protective coatings frequently do not sufficiently protect steel screws against corrosion in outdoor areas. Rust is not just ugly but also expensive. In particular, if the quality of expensive products or components deteriorates and results in consequential damage.Costly reworks and repairs become necessary. Rust can be avoided. The SPAX rust-free stainless steel offers protection against corrosion.
