Wovar Stainless steel screws for Oak & Garapa hardwood

Wovar supplies special stainless steel screws for wood types containing tannic acid. Examples include Oak, Garapa, Red Cedar and Kapur. These durable woods contain extreme tannic acids that attack 410 stainless steel screws and galvanized screws. The stainless steel screws from Wovar for Oak & Garapa hardwood have a special anti-tannic acid coating. This coating protects the screw against tannic acid, so that the screw is not affected.

Always use these special anti-tannic screws for wood types containing tannic acid. This prevents broken screws and black spots in the wood. In addition to Oak and Garapa, these screws are also suitable for Red cedar and Accoya wood.

For hardwoods with little or no tannic acids, we recommend using our 410 stainless steel decking screws or garden screws. Our coated screws are also very popular for outdoor purposes!

This stainless steel screw, specifically designed for hardwood types that contain tannic acid, is no less than twice as strong as normal stainless steel screws. The core of the screw contains hardened steel. This means you do not suffer from breaking screws. Even if the wood starts tearing after screwing in, these special hardwood screws do not break. The organic anti-rust / anti-tannic coating is highly corrosion-resistant and consists of 3 layers. It is not a problem if the coating is damaged while screwing in the screw. The coating recovers, so that optimal protection is retained.


Hardwood screws with tannins

The excellent chemical and tannic acid resistance of the coating makes this screw extremely suitable for wood types such as Kapur, Red Cedar, Oak and Garapa. In addition to these advantages thanks to the coating, this screw also has a serrated starter thread, a wax layer and a coarse pitch. These specifications ensure fast processing and low screw-in resistance.

Pre-drill and countersink the head

The screws are fully threaded, so it is recommended to pre-drill slightly for wood on wood structures. Milling ribs are incorporated under the countersunk head. These ensure a beautiful recess in the wood. If you are going to mount decking boards, we recommend using our countersink drill. This ensures a beautiful and complete countersink of the head. The extra deep Torx impression ensures that your machine does not slip while screwing in the screw.
