Screw SPAX BLAX 16 mm Steel 200 pcs

SPAX BLAX screw, 16 mm, steel, pack of 200. This full-thread wood screw features a flat countersunk head with a polygonal underside and a T-STAR plus (hexalobular internal) drive for optimal bit engagement. The 4CUT arrow-shaped tip displaces wood fibres during insertion to reduce splitting and lower the required cordless‑driver torque. The black finish makes the screw suitable where a dark appearance is required.

Advantages

The T-STAR plus drive provides a large contact surface and precise bit positioning to maximise force transmission and minimise bit cam‑out. The flat countersunk head with milling pockets allows the head to sit flush without pre‑countersinking in many wood types. Full threading over the screw length increases tensile and compressive load transfer for reliable wood connections. The 4CUT tip reduces wood splitting and often eliminates the need for pre‑drilling, saving time and battery power when using cordless drivers.

Suitable for

• Fastening window and door frames with plastic or aluminium profiles
• Heavy‑duty wood connections in structural joinery
• Interior fittings and furniture assembly with dark or black fittings
• Applications where concealed, flush heads are required

How to use

Select a correctly sized T-STAR plus bit and secure it in the cordless or corded driver. Position the 4CUT tip on the marking and drive the screw until the flat countersunk head sits flush with the work surface. For dense or highly stressed wood, check whether pre‑drilling is recommended; in many common wood types and near edges the 4CUT tip and milling pockets allow insertion without pre‑drilling. Apply steady axial pressure and allow the driver to control speed to avoid over‑driving the head.

Usage recommendations

Use the SPAX BLAX 16 mm screws with a T-STAR plus bit for fast, low‑slip assembly in wood. For best results in hardwoods or when exact countersinking depth is critical, test on a scrap piece first and consider pilot holes where specified by the wood manufacturer.
