We have designed our ROCO™ Wood to Steel Screw specifically to grant you an extraordinary holding power and leave any job or project with a clean and elegant finish!

When the screw goes into the wood, it drills an oversized hole with the help of its milling wings. This prevents the threads to go into the wood. When the screw hereafter engages the steel base, the wings break off allowing the threads of the screw to anchor into the steel. The milling wings therefore ensures a strengthened and tightened connection between the wood and steel.

Furthermore, the screw is equipped with a thoroughly engineered drill point specifically designed to cut fast through the steel and make sure the threads firmly secure the wood and steel together.

Our ROCO™ Wood to Steel Screw is incredible for any size job or project and is even coated with ZYTEC™ GX corrosion protection coating to make it a great choice for any typical exterior or interior surrounding!

The ROCO™ Wood to Steel General Exterior Screw has following quite special features:

Horizon Curve™

A subtle curvature of the head of the screw allowing it to provide professional and elegant architectural results. The Finish Ring positioned underneath the head likewise administers a refined finish result as it cuts the top fibers in the wood taking an extra step in countersinking.

Superior Drill Point

The drill point of the screw is designed to go through the steel as quickly as possible. The angle and shape of the drill point makes it possible to remove chips of steel extremely fast and efficiently to intensify penetration.

Turbine Ribs™

Our Turbine Ribs™ with patents pending allow the screw to cut immediately into the wood providing an elegant and professional finish with maximum wood contact. Additionally, the cup shaped, countersinking head of the screw increases holding power and diminishes the risk of wood splitting.
