Wafer Head Screws Coated for Oak and Garapa Hardwood

When you are working with hardwood, you want to be sure that you are using the correct screws. These wafer head screws are also referred to as washer head screws, construction lag screws, and structural screws. Wovar’s coated wafer head screws have received an extra AR-coating. This coating protects the screw against the tannic acid present in hardwood. The coating consists of several layers, which means the coating can fix itself when damaged. This creates permanent protection against corrosion as well as tannic acid. Combined with the strength of galvanised steel, these screws are perfect for heavy, hardwood structures.

Wovar also offers wafer head screws in galvanised steel, yellow galvanised steel, A2 stainless steel, A4 stainless steel, and with a black head.

Wafer head screws for oak and garapa are comparable to stainless steel wafer head screws. These screws for hardwood also do not rust. The biggest difference between the two is the strength of the screw. The base of the coated screws is galvanised, hardened steel. This is twice as strong as stainless steel. Thanks to the organic coating with corrosion classification C4, the wafer head screws are protected against tannic acid and corrosion.

When to choose for coated wood screws

You do not have to be afraid to damage the coating when driving in the screw because the coating is self-repairing. Go for coated screws when you work with hardwood containing tannic acid. Examples of hardwood with tannic acid are oak, garapa, kapur, and red cedar wood. The large head of the screws results in a large load-bearing capacity and high clamp force.

An example: are you building a carport with oak posts? Coated screws are the perfect screws to use in this situation.

Pilot holes and countersinking

Due to the strength of the screw, the likelihood of breaking is close to zero. However, we do always recommend drilling a pilot hole when working with hardwood. For an 8 mm thick coated screw, you will have to drill with a 6 mm thick hardwood drill bit. For long screws, use an auger drill bit. Make sure the pilot hole is at least 70% of the required size for the screw. This ensures the screw will not break and will go straight down into the wood. 

Do you want the top of the wafer head screw to be flush with the wood? You can countersink the coated screw by drilling a 4 mm deep hole with a 22 mm wide spade drill bit.
