Wafer Head Screws A4 Stainless Steel 6.0 x 100 mm Torx 25 - box 100 pieces

These wafer head screws are perfect for building wooden structures. The wood screws are also referred to as washer head screws, construction lag screws, and structural screws. Examples of structures built with these screws are gazebos, cabins, and storage sheds. The wafer head screws are partially threaded. The advantage of this is that it leaves no gaps in wood-to-wood connections. The stainless steel wafer head screws are not as strong as the galvanised version. However, the advantage of stainless steel screws is their rust-resistance. Make sure you use the correct torx 25 bits to drive in the screws.

Advantages of stainless steel

The head of the wafer head screw measures 15 mm. This wide head is the reason for the high bearing surface and clamping force. The screw is made from A4 stainless steel. Due to the sharp cutting point, drilling a pilot hole is not required for softwood. We do recommend pre-drilling with a 4 mm hardwood drill bit when you are working with hardwood.

Stainless steel wafer head screws are often used for wooden structures made from oak wood. In contrast to galvanised wafer head screws, stainless steel wood screws are not affected by the tannic acid in the wood.

A2 vs A4 stainless steel

Both A2 and A4 stainless steel screws are corrosion resistant. The main difference between the two types of steel is in the composition. Because A4 stainless steel has a slightly different composition than A2 stainless steel, it is even more corrosion resistant. This makes A4 stainless steel fasteners especially popular in coastal regions and for marine purposes, as well as for use in swimming pools. A4 stainless steel screws are also slightly stronger than A2 stainless steel screws.
