Wood and multi-purpose screws SPAX T20 countersunk head WIROX 4×25 mm, box 1000 pcs

Pack of 1000 SPAX universal wood and multi-purpose screws with a countersunk head, 4 mm diameter and 25 mm length. These SPAX screws feature a T20 drive for precise bit engagement and a WIROX surface treatment that improves corrosion resistance and provides a consistent finish. Intended for a variety of fastening tasks, the screws are suitable for furniture assembly, carpentry, renovation and general-purpose fixing where a countersunk head is required.

Advantages

SPAX screws with T20 drive provide reliable torque transfer and reduced cam-out during installation. The countersunk head sits flush with the material surface when properly driven, creating a neat finish and allowing for subsequent surface treatments. The WIROX coating offers enhanced corrosion protection compared with untreated steel, extending service life in indoor and some sheltered outdoor applications. Supplied in a box of 1000 pieces, the pack supports larger projects and reduces the need for frequent reordering.

Suitable for

• Furniture assembly and fittings
• Interior carpentry and joinery
• Renovation and repair tasks
• Fixing wood to wood and wood to light substrates
• General-purpose fastening where a countersunk finish is desired

How to use

Select an appropriate T20 bit and a compatible power driver or screwdriver. Pre-drilling is optional for softwoods but recommended for hardwoods or when working close to edges to prevent splitting. Drive the screw until the countersunk head is flush with the surface; avoid overdriving to prevent damage to the head or the coated finish. For repeatable results, use a torque-limited driver or set the clutch on the drill to a suitable level.

Usage recommendations

Store the screws in a dry environment to preserve the WIROX coating. For exterior or constantly wet conditions, consider selecting fasteners rated specifically for prolonged outdoor exposure. When working with thin panels or delicate finishes, practice on a scrap piece to set correct torque and depth.
