Spax® Screw, Countersunk Head with T Star, Stainless Steel

Product Details

Are these Spax® screws suitable for use with wood and sheet materials?

Yes. Spax® Scr Ful Csk TS20 D4.0x45mm SS screws are designed for practical fixing in wood, chipboard, plastic and sheet metal. They are a good choice when you need a clean countersunk finish.

Will the 45 mm length suit a typical through fixing into timber?

Length 45 mm is commonly used where you need solid engagement into the substrate while still allowing the head to sit correctly when countersunk. Choose the length so you get reliable hold without bottoming out in the material.

Do I need a special tool to drive the TS20 Torx head?

Yes, you will need a TS20 Torx drive driver or bit. Using the correct drive size helps improve control and reduces the risk of cam out when driving the screw.

Are these fully threaded, and does that affect holding power?

They are fully threaded. Fully threaded screws typically provide a consistent grip along the full length of the screw, which can be helpful for secure fastening, especially where you want the thread to bite through the full material thickness.

What does the countersunk head mean for my finished surface?

Countersunk head means the screw head is designed to sit flush with, or below, the surface when used with the appropriate countersink. This helps deliver a neater finish, particularly for flat trim work and board fitting.

Is stainless steel protection useful for indoor and outdoor projects?

These screws are stainless steel, which is well suited to applications where corrosion resistance matters. They are a reliable option for many general fixing jobs, including projects that may be exposed to moisture in typical home and workshop conditions.

How many screws are included in the pack?

You get 200 screws per pack, which is convenient for completing multiple jobs or stocking up for regular use.

What is the thread diameter, and why does it matter?

Thread Ø 4.0 mm indicates the screw thickness. It matters because it affects compatibility with pre drilling, pilot hole sizing, and the strength of the connection. For the best results, match the screw size to your fixing requirement and the material thickness.
