3.5 x 49mm Tongue-Tite Black Stainless Steel TX Countersunk Screws - Box of 200 (TFTTSB03549)

Hidden Fixing for Timber Flooring and Cladding

Black stainless-steel screws designed specifically for installing tongue and groove flooring, timber cladding and other tongue-and-groove boards where a discreet, secure and removable fixing is required.

Manufactured with a small and narrow countersunk head that sits neatly on the groove of the tongue of the board. This allows the following board to cover the fixing which create a clean join with the screw being concealed.

Manufactured with a twin thread tip allowing fast insertion and a single coarse thread that drives the screw in easily with high pull-out resistance.

Tongue Tite Screws are manufactured with a high core strength to prevent snapping, even when the material flexes.

The black stainless steel finish is particularly suited to external timber applications and dark or charred timber cladding, where a black fixing provides a much less noticeable appearance than conventional bright stainless steel.
