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
