Product description:

Flat countersunk head, T-STAR plus

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
