Self-tapping screw with rubber washer

A self-tapping screw with rubber washer is a fastener in the form of a threaded rod with a hex head, under which there is a rubberized gasket protected by a metal washer. The tip of the working part can be pointed or drill-shaped.

The following variants are available:

• various sizes in length and diameter;
• fine, coarse, or variable thread pitch;
• versions for use with wood, metal, concrete, and other dense materials;
• versions for fastening roofing materials, sandwich panels, facade cladding;
• coating — plain zinc or RAL-painted.

The rubber washer under the head ensures tight contact between the joined surfaces. The gasket prevents moisture from getting under the fastener, reduces the risk of the screw loosening on its own, and increases the strength of the connection. Choosing the coating color allows the fastener to match the appearance of the structure.
