Screw SPAX BLAX 16 mm Steel 200 pcs

SPAX BLAX 16 mm steel screws are designed for woodworking tasks that require secure, flush fastening with a discreet dark finish. Each screw is 16 mm long with a 6 mm flat countersunk head and full thread running along most of the shank. The black steel surface and flat countersunk design make these screws suitable for use with dark furniture or fittings and allow the head to sit flush with the workpiece.

Advantages

The T-STAR plus hexalobular internal drive provides a large contact surface and precise bit positioning to maximise torque transfer and reduce bit cam-out. The 4CUT arrow-shaped tip displaces wood fibres to reduce splitting and lowers the required cordless screwdriver torque, often eliminating the need for pre-drilling. The flat countersunk head with polygonal underside mills into the wood so it can be countersunk cleanly and sits flush with the surface.

Suitable for

• Fastening window and door frames with plastic or aluminium profiles
• Decorative furniture and fittings, especially dark or antique woods
• General wood connections in interior construction
• Applications where a flush, low-profile head is required

How to use

Select the correct T-STAR plus bit for your cordless screwdriver or driver. Position the screw perpendicular to the workpiece and apply steady pressure while driving at moderate speed to allow the 4CUT tip to displace fibres and the polygonal underside of the countersunk head to mill into the wood. For hardwoods or sensitive edge areas, consider using reduced speed or a guiding pilot hole. Drive the screw until the flat head sits flush with the surface.

Usage recommendations

Use the SPAX BLAX 16 mm screws for interior woodworking and decorative fittings where a flush, dark finish is desired. In most softwoods and many composite boards pre-drilling is not necessary thanks to the 4CUT tip and countersinking underside; test on a scrap piece when working near edges or in dense hardwood to confirm suitability.
