JCP Fixings Metalfix Stitching Screws are professional-grade fasteners designed for contractors and DIY enthusiasts working on cladding applications. They offer superior durability and quick, efficient installation thanks to their engineered design and included 16mm washers. While they provide excellent corrosion resistance, users should ensure they are using the correct drive tool to avoid stripping the screw head during high-torque applications.

While they feature enhanced corrosion resistance, they are primarily designed for standard construction. For severe coastal environments, check specific salt-spray resistance ratings.
No, these are self-drilling screws designed to penetrate metal directly.
The washer provides extra load-bearing surface and helps create a tight, weather-resistant seal against the cladding surface.
These are specifically designed for metal-to-metal cladding applications, not for wood.
They are manufactured in accordance with the DIN 7504K standard for self-drilling screws.
The washer is designed to be a permanent part of the fastener assembly for optimal stability and support.
Verify the thickness of the metal being drilled; ensure you are using the correct speed and pressure on your drill.
This indicates the hole has been over-drilled or the metal is too thin to hold the threads. Consider using a slightly larger diameter fastener.
Check that the driver bit is the correct size and fully seated in the head of the screw. Reduce the torque setting on your drill.
To ensure the best performance, use a high-quality impact driver with a depth-sensitive nose piece to prevent overtightening. These screws are compatible with most standard metal cladding materials. When storing, keep the screws in their original packaging in a dry environment to maintain their protective coating integrity. Avoid using impact drivers at maximum power settings on thinner gauge metals, as this may strip the threads or damage the washer seal.
