If you screw the black screws into hardwood, it is necessary to pre-drill. This is easy with our 3 mm thick hardwood drill. The black garden screws, also known as cup lid screws, are equipped with a Torx 20 drive. This extra deep Torx impression ensures that your machine does not slip while screwing in. The black screw has a countersunk head with milling ribs at the bottom. This ensures a good galvanising in the wood, making the finish even more beautiful.

410 Stainless Steel Black Garden Screws

The head of the screw is treated with a special powder coating. This coating is of high quality and therefore has high wear resistance. The stainless steel 410 wood screw with a black head is hardened by means of special heat treatment. Here the black wood screws are first heated and then cooled quickly. In addition to the heat treatment, the screws are high-quality galvanised in a zinc bath and contain a razor-sharp cutting point.

The black garden screws from Wovar have shank ribs. These take the tension off the screw and ensure that optimum power is retained. The shank ribs also provide less resistance when driving the screws. This allows your machine to fit more black garden screws per battery charge.

410 Stainless steel garden screws with a black head are available in 6 different lengths. The thickness is always 4.0 mm. The lengths vary from 35 to 80 mm. This makes the black garden screws suitable for mounting, for example, pot lid planks of different thicknesses.

Wovar is a renowned brand for very strong stainless steel screws for use in the garden. This particularly popular product is more than worth the investment. Are you going to mount black pot lid planks with these black screws? Always use a 2 mm gap (at the back) between the boards. Never stack tightly on top of each other. Always place 2 cup lid screws at 1/3 and 2/3 of the plank width for each plank.

Galvanised Black Garden Screws

The black Torx screws made of galvanised steel have a Deltacoll coating. This coating provides high corrosion resistance and protects the black screws against rust and oxidation. Then a black top layer was applied to the screws. This top layer provides a beautiful shine. The black galvanised screws have a Torx impression. This gives your machine a lot of grip and does not slip when the screw is screwed in.

The galvanised steel makes these black screws very strong. Just like the 410 stainless steel black screws, the screws have a razor-sharp cutting point. This ensures that the thinnest sheet material does not split and makes pre-drilling in softwood unnecessary. Pre-drilling is recommended for hardwood. This is easily possible with one of our hardwood drill bits. For each screw, it is indicated which size you can best use for this.
