FAQ

Product Details

Is this SPAX screw suitable for general fixing jobs with a countersunk finish?

Yes. The Spax Scr Ful Csk TS20 D4.0x45mm Wrx is designed with a countersunk head so it sits flush when driven correctly, making it a good choice for tidy, professional looking fixings in a range of wood based applications.

What drive type do I need to install these screws?

You will need a T Star Torx style bit. This model uses a TS20 drive, so using the correct bit helps reduce cam out and improves the chance of a clean, secure installation.

How does the 4CUT tip help when fitting?

The 4CUT tip is designed to cut into wood efficiently. It helps the screw start cleanly and maintain consistent cutting during driving, which can make installation smoother and reduce the need for pre drilling in many typical wood fixing tasks.

Are these screws fully threaded, and what difference does that make?

Yes, they are fully threaded. Fully threaded screws grip along the full length under the head, which can improve pull through resistance and helps the joint stay tight, particularly for structural or load bearing style fixings.

What size are the screws, including diameter and length?

Length is 45 mm and the thread diameter is 4.0 mm. This size is commonly used for general timber fixing where a solid bite is needed.

Do these screws have corrosion protection for use outdoors?

They are galvanized, zinc plated. This provides corrosion resistance for many external and damp area applications, although performance can still depend on the surrounding conditions and timber type.

How many screws are included in the pack?

The pack contains 200 screws. A 200 pack is useful for both repeat projects and larger jobs where you want to keep supplies consistent.

Are these screws building regulations approved?

Yes. This product is Building regulations approved under Z 9.1 235, which can be helpful when you need compliant materials for relevant building work.
