Screw SPAX BLAX 30 mm Steel 200 pcs

SPAX BLAX screw, 30 mm length, steel construction and supplied in a pack of 200 pieces. Designed for fastening in wood, this full-thread screw features a flat countersunk head and a T-STAR plus (hexalobular internal) drive to ensure high contact surface and optimal bit positioning. The 4CUT arrow-shaped tip displaces wood fibers during insertion, reducing splitting and lowering the torque required from a cordless screwdriver. With a thread length of 26 mm and a head diameter of 6 mm, the screw is suitable for a wide range of interior and structural wood connections, including plug-free installation of window and door frames.

Advantages

The T-STAR plus drive provides maximum, precise force transmission from the screwdriver to the screw, minimising bit slip and enabling faster serial fastening. The flat countersunk head with polygonal underside mills into the wood and sits flush with the surface, avoiding obstructive screw heads inside frames. Full thread along most of the screw increases tensile and compressive load capacity for heavy-duty wood connections. The 4CUT tip reduces core expansion and wood splitting, often eliminating the need for pre-drilling and reducing required driver torque.

Suitable for

• General woodworking and interior joinery
• Installation of window and door frames with plastic or aluminium profiles (plug-free fastening)
• Structural wood connections requiring high tensile/compressive strength
• Decorative furniture and fittings in dark or black finishes

How to use

Select a T-STAR plus bit that matches the hexalobular recess and fit it to a cordless screwdriver or drill. Position the screw perpendicular to the workpiece and start driving at moderate speed; the 4CUT tip will displace fibres and the polygonal underside of the flat countersunk head will mill into the surface so pre-drilling is usually not required depending on the wood species and edge proximity. Apply steady pressure and avoid excessive torque once the head is flush with the surface to prevent overdriving.

Usage recommendations

For best results use with an appropriate T-STAR plus bit and a cordless driver with adjustable torque. Test on a scrap piece when working near edges or with hard wood species to confirm whether pre-drilling is necessary. Store screws in a dry place to prevent corrosion.
