Strong outdoor fastening with Spax

Practical benefits

Maximum driver bit grip: The T-STAR plus T20 recess prevents slipping and gives you optimal torque transfer while driving.
Corrosion resistant A2 steel: You achieve durable weather resistance for outdoor timber applications thanks to the stainless steel.
Clean and flush finish: The countersunk head sinks smoothly into timber so you get a completely flush surface.

In a nutshell

The right choise for

With Spax chipboard screws, you create strong and clean timber joints in outdoor areas and damp spaces. The weather-resistant A2 stainless steel protects your assemblies against rust and corrosion stains. Driving is fast and controlled thanks to the t-star plus T20 recess, which prevents bit slip and transfers torque efficiently. The countersunk multi head sinks smoothly and flush into the wood surface without splitting, while the full thread provides robust anchoring along the entire 25 mm length. This allows you to complete every fastening job quickly, neatly, and with long-lasting holding power.

Product description:

Flat countersunk head, T-STAR plus
With MULTI Head and 4CUT, synthetic coating
Stainless steel A2 II

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.

Special properties:

Stainless steel A2 II: high corrosion protection
T-STAR plus: secure bit grip, no cam-out effect, optimal force transmission

Features:

4CUT: allows screwing in without pre-drilling (wood-dependent), reduces splitting as square end displaces the fibres
Ground serrations: up to the point - quick and secure fastening
MULTI Head: flush countersinking. Mills in wood and stops on metal
