Clean board assembly with Spax

Practical benefits

Split free board driving: The specialized cut point lets you drive directly without pre-drilling while preventing fiberboard edges from splitting or bulging.
Smooth flush countersinking: A slim milling head pulls cleanly into the timber panel, leaving you with an even and professional finish.
Reliable torque control: The T20 drive recess eliminates cam-out so you can drive screws firmly without slipping off the head.

In a nutshell

The right choise for

With the Spax mdf screw 4 x 50 mm, you can assemble delicate board materials reliably without splitting or bulging. Thanks to the specialised cut point, you drive directly into mdf and chipboard without pre-drilling, even close to edges or into end grain. The partial thread pulls your workpieces tightly together, delivering a clean, gap-free joint when building cabinets, furniture carcases, and interior fittings. Its slim countersunk milling head sinks neatly flush with the surface for a smooth finish. The t-star plus T20 recess provides slip-free torque transfer, while the wirox coating delivers dependable indoor corrosion resistance.

Frequently asked questions about this product

Answered by specialists

Do you need to pre-drill in MDF?: Pre-drilling is generally not required thanks to the CUT point, which effectively reduces splitting and bulging.
Which driver bit should you use?: You need a T-STAR plus or standard Torx bit in size T20.
What is the purpose of the partial thread?: The partial thread pulls the top board tightly against the lower piece, ensuring a gap-free joint.
What are the benefits of the WIROX coating?: The WIROX finish delivers significantly higher corrosion resistance than standard zinc plating for indoor joinery.
Does the screw head sit flush in the board?: Yes, the small 75° milling head countersinks cleanly and flush into the board surface.
