Flat Head: The head of the screw is flat, allowing it to sit flush with the material surface. This is ideal for applications where a smooth, even finish is required.

Wings: These screws have small metal wings just above the drill point. The wings are designed to create a larger hole in softer materials before breaking off when they hit the harder material. This prevents the softer material from riding up the threads and ensures a tight and secure fastening.

Self-Drilling: The tip of the screw is designed to drill its own hole as it is driven into the material. This eliminates the need for a pre-drilled pilot hole, saving time and effort during installation.

Screw of union of all type of wood to plates and profiles of steel. • The fins of the drill bit allow to oversize the hole in the wood, avoiding 2 problems: 1. Perform annoying and expensive previous drills 2. The separation between wood and steel, being an incorrect and problematic assembly, both functionally and aesthetically. • With grooves under the head to be fully flush in the wood
