Button Head Wafer Screws

With our galvanized and stainless steel structural screws, also known as construction lag screws, lag bolts, flange button head screws, or simply, wood construction screws, from Wovar, you can quickly and easily mount large wooden construction projects, like a larch douglas roof. Our lag screws are available in three different types. These are yellow galvanized steel, grey galvanized steel, and stainless steel, and are also available in black. Lag Screws have a large built-in washer head for strong wood binding.

The lag screw is sometimes called the successor of the wood screw, because due to its Torx head, it makes assembly work go by much faster. Because of the wide disc head, these screws provide a good hold. This flanged head screw is therefore widely used in timber construction, for connecting posts to roof beams.

In addition to structural screws, Wovar also supplies high-quality carriage bolts and coach screws. Additionally, we also recommend you keep in mind our assortment of small hardware such as carabiners, wind hooks, and snap hooks.

Wovar always has structural screws in stock. Are you making a wooden construction from Larix Douglas wood? Then choose our yellow galvanized construction lag screws. These look beautiful on Larix Douglas wood and are just a bit stronger than our gray galvanized lag screws. Our best sellers are the 8 x 80mm and the 8 x 100 mm lag screws. This size is sufficient for mounting 5 x 10 and 5 x 15 beams. Are you looking for even longer screws with a large head? We also have these mounting screws with built-in washer heads available in long sizes, such as 200 mm and 220 mm.

For lighter and outside constructions, such as a wheelie bin storage, we recommend our stainless steel lag screws. Stainless steel is softer than galvanized steel. This also makes a stainless steel structural screw a little less strong, and therefore, less suitable for heavy constructions. The greatest advantage of our stainless construction screws is that they do not oxidize. The galvanized lag screws can oxidize after damage to the zinc layer.

To minimize the risk of zinc-plated lag screws being damaged, it is important that you install the construction lag screws with high-quality bits. Wovar has various bits and bit sets available for you. These have a perfect fit on the Torx impression of the Wovar structural screw.

Tip: To countersink the Wovar lag screw, use our 24 mm spade drill.

Galvanized structural screws are always stronger than the stainless steel version. However, the galvanized version can oxidize slightly, which does not happen easily with stainless steel. Order the high-quality construction lag screws made of grey galvanized, yellow galvanized, or stainless steel from Wovar now, for the lowest price. Companies in the construction and garden industry benefit from additional benefits such as discounts with a business account.
