Stainless steel screws 4 x 40 mm for Oak and Garapa hardwood - Box 200 pieces

Stainless Steel Screws for Hardwoods with extreme tannins such as oak, Red Cedar and Garapa wood exclusively available at Wovar. This 4 x 40 mm screw has a special coating that offers protection against tannic acids that occur in many hardwoods. The coating gives this screw a grey color. You do not have to worry that the coating will be damaged when screwing in the screw. The anti-tannic acid or anti-rust coating has a self-healing effect. As a result, minor damage is trivial.

When using screws that do not have a protective coating, you will get a black stain on your hardwood within 48 hours. This is the work of the tannins that contain the wood. Therefore, always use our special stainless steel screws with protective coating for Oak wood, Garapa wood, Accoya wood and Red Cedar wood.

Screws for oak wood, Garapa wood and Red Cedar

The screws for oak, Garapa wood and Red Cedar 4 x 40 mm are fully threaded. It is therefore recommended to pre-drill with a 3.0 mm thick hardwood drill. By pre-drilling you prevent the chance of an interspace with wood on wood constructions and the screw can pull the loose parts against each other. The torx 20 impression ensures that your machine does not slip while screwing in the screw. The lower part of the thread is serrated. This makes it easier to cut through hardwood. Always use a high-quality torx 20 bit from Wovar to prevent damage to the head.

Milling ribs are located under the countersunk head. These ensure a beautiful recess in the wood. Do you want the head to disappear completely into the wood? Then use our galvanised drill bit 4 mm. Just drill for 2 seconds and you will see that the head sinks beautifully.
