SPAX universal screw, countersunk head 3x40/23 T10 Wirox (1000 pcs/pack)

The SPAX T-STAR plus drive ensures maximum power transfer to the screwdriver. Thanks to its unique hexalobular design, fastening is fast, precise, and slipping is a thing of the past. The bit fits perfectly into the screw head, making repetitive fastening easy and efficient.

A thin yet durable head is especially important when installing window and door frames. The fully threaded SPAX-RA screw is designed specifically for this purpose. It fastens without plugs and allows for a clean finish without protruding heads.

The full thread extends along almost the entire length of the screw, allowing it to withstand significantly higher tensile and compressive loads than a partially threaded screw. This makes it an excellent choice for demanding wood joints, for example in structural applications, without unsightly metal connectors.

The 4CUT point shapes the screw tip like an arrow, allowing the wood fibers to be cleanly displaced during driving. This reduces the risk of splitting, especially near edges, and lowers the torque required from the tool. In most cases, there is no need for pre-drilling.

For outdoor use, screws must offer durability. The WIROX coating provides excellent corrosion protection without environmentally harmful chromium(VI). WIROX screws are an ideal solution for structures that are outdoors but not directly exposed to the elements, such as pergolas and carports. If the structures are directly exposed to rain and moisture, we recommend stainless steel screws.
