Reliable chipboard screw for woodworking

Practical benefits

Optimal torque transfer during fastening: The T20 drive provides a secure bit fit so you can drive screws smoothly without slipping.
Clean and flush finish: The countersunk head sinks neatly into the wood surface, leaving you with a smooth, professional result.
Strong hold with full thread: The full thread delivers superior grip and high pull-out resistance throughout your timber joints.

In a nutshell

The right choise for

With the Spax chipboard screw 5 x 50 mm, you achieve strong and clean timber joints indoors. The full thread across the entire 50 mm length delivers maximum grip and superior resistance to tensile and compressive loads. With the t-star Plus T20 drive, you get direct torque transfer without bit slippage. The countersunk multi head sinks flush into the wood surface without needing prior countersinking in softwoods. Thanks to the black zinc-plated finish, this screw is ideal for assembling dark furniture, MDF, chipboard, and matching black decorative fittings.

Product description

Multifunctional application indoors
Fast and reliable processing with low effort (more screws on one battery charge)
Application in decorative furniture construction when using dark/antique woods or dark furniture/metal fittings
Effectively reduces the risk of the wood splitting, even with small edge distances
Visually attractive appearance with black fittings and dark wood types
Without pre-drilling (depending on the type of wood)

The universal screw is the absolute all-rounder in the SPAX 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 practically completely prevented.

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