Which driver bit do you need for these screws?

Use a T-STAR plus T20 bit (Torx) for a secure fit and optimal torque transfer.

Are these screws suitable for outdoor use?

Yes, thanks to A2 stainless steel, these screws are resistant to moisture and outdoor weather conditions.

What is the benefit of the multikop countersunk head?

It countersinks flush into wood and brakes on metal to avoid over-tightening on fittings.

Do you need to pre-drill before driving these screws?

Pre-drilling is not required in softwoods or board materials, but it is recommended for hardwoods.

What is the main advantage of a full thread?

Full thread provides strong holding power along the entire length, absorbing tensile and compressive forces well.

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
