Screw SPAX BLAX 30 mm Steel 200 pcs

SPAX BLAX screws are steel wood screws designed for reliable fastening in interior and structural wood applications. Each screw is 30 mm long with a thread length of approximately 25 mm and a flat countersunk head with a head diameter of 9.6 mm. The BLAX finish provides a dark appearance suitable for dark woods and fittings. The pack contains 200 pieces, manufactured in Germany for consistent quality.

Advantages

The combination of the T‑STAR plus hexalobular internal drive, full thread and 4CUT tip gives high transmission of torque, reduced bit slip and efficient, fast driving with cordless tools. The flat countersunk head has a polygonal underside that mills into the wood so the screw can be countersunk flush without pre‑drilling in many common woods. The 4CUT arrow‑shaped tip displaces wood fibres to reduce core expansion and minimise splitting, lowering the required driver torque.

Suitable for

• Interior woodwork and decorative furniture where dark screws are preferred
• Installation of window and door frames with plastic or aluminium profiles (plug‑free fastening)
• Heavy‑duty wood connections and structural timber joints
• Fast serial fastening with cordless drivers to increase work speed

How to use

Select a matching T‑STAR plus bit in the correct size and mount it in a cordless screwdriver or drill driver. Position the screw perpendicular to the workpiece and apply steady pressure while driving at controlled speed. In many common woods the polygonal underside of the flat countersunk head mills into the surface, allowing the head to sit flush without pre‑drilling; however, when working near edges, in very hard or brittle woods, or where exact positioning is critical, a pilot hole is recommended. Use appropriate safety equipment and clamp workpieces to prevent movement.

Usage recommendations

For best results use a T‑STAR plus screwdriver bit and moderate driver speed. Avoid excessive torque to prevent over‑countersinking in soft woods. When installing window or door frames, ensure the screw length and profile penetration are appropriate for the frame material and any connectors used.
