Reliable timber fastening with Spax

Practical benefits

Superior bit engagement: The T-STAR plus drive prevents cam-out so you can transfer power cleanly and securely during fast repetitive driving.
Clean flush surface finish: The countersunk head sinks neatly into the timber, allowing you to achieve a smooth finish without additional pre-countersinking.
Enhanced corrosion resistance: The WIROX surface coating provides you with substantially higher protection against oxidation compared to standard zinc coatings.

In a nutshell

The right choise for

With Spax 3.5 x 20 mm chipboard screws, you achieve strong and clean timber connections across wood, chipboard, and mdf. The t-star plus T20 drive ensures a secure bit fit to prevent cam-out and maximise power transfer during rapid fastening. Thanks to the countersunk multi-head, the steel screw sinks smoothly flush with the surface without splitting the material or requiring pre-drilling. Its full thread delivers high tensile strength to firmly hold furniture hardware and thin panels in place. Finished with the durable Wirox coating, this 200-piece pack provides superior indoor corrosion protection compared to standard zinc-plated screws.

Frequently asked questions about this product

Answered by specialists

Which screw bit is required for this screw?: You need a T-STAR plus T20 or standard Torx T20 bit for a secure grip during driving.
What is the benefit of the WIROX coating?: The Spax WIROX coating provides significantly higher corrosion resistance than standard zinc plating indoors.
When should you choose a fully threaded screw?: Full threading delivers high tensile strength and prevents movement when fastening fittings or thin boards.
Do you need to pre-drill in softwood?: Pre-drilling is generally not required in softwoods thanks to the sharp point geometry.
