The SS8 Confirmat Screws are essential for professional woodworkers and DIY enthusiasts looking to assemble rigid, long-lasting furniture from MDF, chipboard, and particleboard. These specialized fasteners provide superior holding power compared to standard wood screws by acting as both a fastener and a structural steel dowel, creating high-strength 90-degree joints. While they offer unmatched structural integrity for flat-pack furniture and custom cabinetry, they require precise pre-drilling and a specific drill bit size to prevent material splitting.

These are specifically designed for engineered woods like MDF and particleboard. They are not recommended for solid wood as the thread geometry is optimized for compressed wood fibers.
Yes, a standard twist drill bit will not work correctly. You need a Confirmat step-drill bit designed for 6.4mm screws to clear the hole for the shoulder and the thread.
Yes, their coarse thread design allows them to be removed and re-installed into the same hole multiple times without significantly losing holding power.
The primary benefit is the unthreaded shoulder, which functions as a steel dowel for added shear strength and alignment, preventing the joints from shifting.
The 50mm length provided in this set is ideal for 18mm-19mm board thicknesses, as it allows for a secure, deep engagement into the adjoining panel.
Verify that the correct diameter drill bit was used; if the pilot hole is too wide, the threads cannot grip the material effectively.
Always pre-drill using a step-bit to remove excess material before inserting the screw, and ensure you are not driving the screw too close to the panel edge.
Ensure the pilot hole is drilled to the correct depth and check that no debris remains inside the hole before driving.
To achieve professional results, you must use a dedicated Confirmat drill bit that matches the 6.4mm diameter. The bit creates the necessary stepped hole: a wider diameter for the shoulder and a narrower diameter for the threaded section.
