## Summary description

SPAX BLAX wood screws, steel construction in black finish, 50 mm length with 3.5 mm nominal thread diameter and 45 mm thread length. Pack contains 200 pieces. Designed for fastening wood and wooden components; suitable for general carpentry, joinery and assembly where corrosion-resistant coated steel screws are required.

## Long description

SPAX BLAX 50 mm screws are full-thread wood screws made of steel with a flat countersunk head and a T-STAR plus hexalobular internal drive. The screws have a 50 mm overall length, an approximately 45 mm thread length, and a head diameter of about 7 mm. Their black finish suits dark woods and fittings and the pack contains 200 pieces. The design combines a full thread for high load transfer, a 4CUT arrow-shaped tip to reduce splitting and eliminate much pre-drilling, and a countersunk head that sits flush in the material.
Advantages
The T-STAR plus drive provides a larger contact surface and precise bit positioning, enabling maximum force transmission from the driver to the screw and significantly reducing bit cam-out. The full thread increases tensile and compressive load capacity along the entire screw length, making the fasteners suitable for heavy wood connections. The 4CUT tip displaces wood fibres to reduce splitting and lowers required insertion torque, while the polygonal underside of the flat countersunk head mills into the wood to allow flush countersinking often without pre-drilling.
Suitable for
Fastening window and door frames in plastic or aluminium profiles without visible obstructive heads
Heavy-duty wood connections in structural or furniture applications
Work with dark woods or black fittings where a discreet appearance is required
Interior joinery and decorative furniture construction
When it may not be suitable
These steel full-thread screws are intended for use in wood and may not be suitable for fastening into metal, masonry, or other non-wood materials. The black finish is decorative but not a corrosion system; for prolonged outdoor or highly humid environments a corrosion-resistant coated or stainless alternative should be considered.
Key specifications
Length: 50 mm
Thread length: approximately 45 mm (full thread)
Head type: flat countersunk with polygonal underside
Drive type: T-STAR plus (hexalobular internal)
Tip shape: 4CUT arrow-shaped point
Material: steel
Finish/color: black
Recommended application material: wood
Quantity per pack: 200 pieces
How to use
Select a T-STAR plus bit of the correct size and fit it securely in your cordless or corded screwdriver. Position the screw at the intended point and start driving at low speed to ensure the bit seats correctly in the hexalobular recess. Increase speed and apply steady pressure; the 4CUT tip reduces the need for pre-drilling in most wood types and the polygonal underside of the countersunk head allows the head to be milled in for a flush finish. For critical structural connections follow applicable building rules and check the required minimum embedment and spacing.
What to consider before purchase
Intended material: these screws are designed for use in wood
Environment: black finish is decorative; choose corrosion-resistant screws for outdoor or humid use
Application load: full-thread design suits heavy-duty wood connections—verify lengths and diameters for your structural needs
Driver compatibility: requires T-STAR plus (hexalobular) bits for optimal performance
Usage recommendations
Use a matching T-STAR plus bit and a suitable torque setting on your driver. For work near edges or in splitting-prone timber, the 4CUT tip typically avoids pre-drilling, but perform a trial in the same material if in doubt. For structural or exterior use, verify corrosion requirements and installation rules before fastening.
