Structural wood screw 8.0x380mm washer head, TX /25pcs/ CS-8380

Wood construction screw

The construction screw with a diameter of 8mm and a length of 380mm is a tool for creating durable connections in wooden structures. Made of low-carbon steel coated with a protective yellow zinc layer.

The product was developed for fastening structural elements made of solid wood, glulam, and wood-based boards. It is effective for fastening rafters to purlins and for mounting chipboards to load-bearing structures. It finds application in the construction of pergolas, gazebos, and sheds.

Thread design

The partial thread allows for firm clamping of the connected elements during the fastening process - a feature that ensures the stability of the entire structure. The ribbed thread surface, coated with a lubricating wax layer, reduces the force required to drive the element.

The drill point located at the tip of the screw eliminates the risk of material splitting even at the initial stage of penetrating the wood structure. This enables safe fastening even with more delicate wood species or when working close to the edges of elements.

Work efficiency and energy savings

The minimized torque required for complete driving translates into energy savings for the tool's battery and extends the service life of the equipment itself. The Torx drive facilitates screw guidance and prevents bit cam-out during work.

The washer head functions as a natural washer - it distributes pressure over a larger surface area of the fastened material and effectively prevents the element from pulling through the working surface.

Practical applications

In the residential construction sector, it is used for erecting roof trusses and mounting load-bearing elements of garden gazebos and wooden terraces. In utility construction, it is effective for creating tool sheds and outbuildings.

In renovation and modernization works, it enables the safe replacement of damaged truss elements without the need to dismantle the entire roof structure. Its length of 380mm ensures sufficient penetration even through thicker structural beams or multi-layered connections.

Electro-galvanized coating with yellow or white passivation provides resistance to atmospheric factors - the product maintains its parameters both indoors and in outdoor conditions exposed to moisture and varying temperatures.
