Clean joining in medium density fibreboard

Practical benefits

Splitting prevention in boards: The specialized CUT point lets you drive screws directly without pre-drilling while preventing edge splitting in panels.
Maximum Spax bit engagement: The precise T-STAR plus T15 recess holds your bit securely to deliver smooth power transfer without cam-out.
Flush and clean countersinking: The narrow countersunk head pulls smoothly into the timber surface to give you a completely flat finish.

In a nutshell

The right choise for

With Spax-M mdf screws, you can join fibreboard and mdf quickly, cleanly, and without splitting. Thanks to the special Cut point, you can drive screws directly into board materials without pre-drilling, even close to edges. The partial thread pulls wooden components tightly together without gaps, while the narrow countersunk head with milling ribs sinks neatly flush into the surface. The precise t-star plus T15 drive delivers optimal power transmission and prevents bit cam-out during screwdriving. Featuring a durable Wirox coating, these 3.5 x 50 mm steel screws provide reliable corrosion protection for furniture making and interior fitting projects.

Frequently asked questions about this product

Answered by specialists

Do you need to pre-drill when using these in MDF?: Thanks to the special CUT point, pre-drilling is generally not required, depending on the wood type.
Which screwdriver bit is required for these screws?: You need a T15 bit (T-STAR plus T15) for optimal grip and efficient power transmission.
What is the advantage of the Wirox coating?: Wirox provides significantly higher corrosion resistance and surface hardness than standard zinc plating.
Why do these screws have a partial thread?: The partial thread pulls the top panel tightly and firmly against the underlying material without gaps.
How does the screw head countersink into the material?: The small 75° countersunk head with milling ribs sinks cleanly into the board for a flush finish.
