SPAX Tellerschrauben 8x100 mm T-Profil Hardened Steel 50 pcs are high-performance wood construction fasteners engineered for demanding timber building applications. Designed to create exceptionally strong and reliable wood-to-wood joints, these screws combine advanced manufacturing with premium materials. Each screw features an 8 mm diameter and a 100 mm length, making them ideal for structural framing, heavy carpentry, and large-scale woodworking projects where holding power is critical. The pack contains 50 pieces, providing a sufficient quantity for professional contractors and dedicated DIY enthusiasts working on robust timber structures.
Advantages
Constructed from hardened steel, these SPAX timber construction screws offer superior strength and durability under high mechanical loads. The specialized large washer head design distributes clamping force evenly across the surface of the wood, significantly increasing the pull-through resistance of the joint compared to standard countersunk screws. The T-Profil drive system ensures optimal power transmission, minimizing cam-out and reducing strain on the tool during installation. Furthermore, the hardened steel composition prevents snapping under torsional stress, ensuring long-term structural integrity in exterior and interior wooden frameworks.
Suitable for
- Heavy-duty timber construction and structural framing
- Building carports, pergolas, gazebos, and wooden sheds
- Attaching roof rafters and major load-bearing beams
- Wood-to-wood joints requiring high pull-through resistance
- Professional carpentry and advanced DIY woodworking projects
When it may not be suitable
These screws are not recommended for fine cabinetry, delicate furniture assembly, or thin wooden boards where the large washer head would be aesthetically intrusive or cause splitting due to its size. Additionally, they are not designed for direct fastening into masonry, concrete, or metal substrates without appropriate anchors.

How to use
Begin by selecting the correct T-Profil driver bit to match the screw head securely. For optimal results in dense or hard wood types, pre-drilling a pilot hole is recommended to prevent wood splitting and to ease the driving process. Position the screw perpendicular to the wood surface and drive it in at a steady, controlled speed using a compatible power drill or impact driver. Ensure the large washer head sits flush against the timber surface without over-tightening, which could strip the thread in the wood.
What to consider before purchase
- Verify that the 100 mm length and 8 mm thickness are appropriate for the thickness of the timber elements you plan to join.
- Ensure you possess a compatible T-Profil driver bit for installation.
- Assess whether the environment requires specialized corrosion protection if used in exposed outdoor locations.
For best results in exterior timber construction, ensure the wood materials are adequately treated against moisture, and always use matching fasteners designed for structural load-bearing applications.
