What are coach screws?
Coach screws are extremely popular because of their hexagonal head. This head creates a screw that can be tightened very well. You can do this by using a ring, open-ended, or combination spanner. Coach screws are often used for securing posts in post holders and with pergola connections. The coach screws ensure a tight and strong connection.
Which coach screw do I need?
Wovar offers galvanised, stainless steel, black, and double-headed coach screws. Galvanised coach screws are incredibly strong, so you are guaranteed a reliable junction. The stainless steel screws can also be used for building structures like canopies, furniture, and playground equipment. Black coach screws are coated with a black coating that also protects the screw against corrosion. The double-headed screws make stripped screws a thing of the past, so you will always be able to easily remove it.

Coach Screws are Bolts with a Pointed Tip
At Wovar, choose from various galvanized and stainless steel coach screws in lengths up to 140 mm. These galvanized bolts were also referred to as wood frets in the past. Wovar's coach screws are made of galvanized steel. With these so-called wood frets, you can, for example, mount plates of concrete bases on wooden uprights.
Our M8, M10, and M12 coach screws are also widely used in wood construction projects such as building roofs and wooden sheds. This is because the coach screws are very strong. We always recommend pre-drilling. This is easy with our 6 mm thick hardwood drills. Prefer to use a Torx screw? Then also view our popular zinc plated wafer head screws or stainless steel chipboard screws.
Galvanized Coach Screws
Galvanized coach screws from Wovar are very strong. This is because the studs are made of galvanized steel. The disadvantage of galvanized steel is that the studs can oxidize or rust after damage to the zinc layer. Therefore try to damage the zinc layer as little as possible. This happens 9 out of 10 times while screwing in. Therefore, always use a ring, wrench, socket, or open-end wrench with the correct wrench size. Then the chance that damage will occur is the smallest.
Stainless Steel Coach Screws
Stainless steel coach screws do not rust or oxidize. Stainless steel coach screws are less strong, however, than galvanized coach screws. This is because stainless steel is softer than galvanized steel. Just like the galvanized bolts, the stainless steel bolts must be mounted with a ring, nut, socket, or open-end wrench with the correct head size.
Black Coach Screws
Wovar's black coach screws are widely used when mounting black hinges. The coach screws have a special Deltacoll® coating and are made of galvanized steel. The galvanized steel ensures that the black studs are very strong. The high-quality black Deltacoll® coating makes the studs resistant to rust and oxidation. The black topcoat has good adhesion that does not come off quickly.
