Firm cabinet assembly with Spax

Practical benefits
  • Strong clamping on panels: The flange washer head evenly distributes contact pressure across panels for a secure, flush connection.
  • Precise bit engagement control: The T-STAR plus T20 drive provides positive bit seating to eliminate slipping during driving.
  • Corrosion resistant nickel finish: Hardwearing nickel-plated steel offers dependable surface protection and a clean aesthetic inside furniture.

In a nutshell

The right choise for

With the Spax cabinet connecting screw, you can assemble carcasses and secure rear panels quickly, cleanly, and securely. The wide flange head distributes clamping pressure evenly across board materials, eliminating the need for separate washers and preventing pull-through. Its partial thread pulls wooden workpieces tightly together without gaps. Driving is smooth and controlled thanks to the t-star plus T20 bit recess, which minimizes slipping and cam-out. In addition, the nickel-plated steel finish delivers dependable corrosion resistance and a neat appearance for all your furniture projects.

The universal screw is the absolute all-rounder in SPAX's range. It can do almost anything - for example, screw into softwood such as spruce and pine completely without pre-drilling or into wooden panels such as MDF, chipboard and OSB boards. Our universal screw shows its superiority especially in interior and furniture construction, but with suitable corrosion protection it can also be used outdoors.

Thanks to its special thread geometry, the resistance when screwing is significantly lower than with conventional screws, which not only protects your muscles and nerves, but also the battery of the cordless screwdriver. Splitting of the wood close to the edges is reliably prevented.

That means for you: you turn in more screws per battery charge and you no longer have to worry about split edges.
