With the Dewalt DFM3130400 spring steel sleeve anchor, you secure timber battens, frames, and profiles into solid base materials like concrete, stone, and solid masonry with speed and confidence. Driving the sleeve directly into a pre-drilled 8 mm hole creates immediate holding power through spring tension, eliminating the need for separate screws or driving tools. Its 130 mm length bridges deeper construction elements during push-through installation. The zinc-plated finish delivers reliable corrosion protection for long-lasting holding strength. Supplied in a practical pack of 50 pieces, this set keeps you working efficiently through extensive fixing jobs.
