Wafer Head Screws A4 Stainless Steel 8.0 x 160 mm Torx 40 - box 50 pieces

These wafer head screws are also referred to as washer head screws, construction lag screws, and structural screws. Wovar's wafer head screws are frequently used to build robust structures, such as a storage shed, small cabin, or carport. These stainless steel wafer head screws are not quite as strong as our galvanised wafer head screws. However, A4 stainless steel possess a host of qualities that makes it a great material for all kinds of purposes. Make sure you use a perfectly fitting torx 40 bit to drive in the screws.

Advantages of stainless steel screws

These screws are often used when building with oak wood. In contrast to galvanised wafer head screws, stainless steel wood screws are not affected by the tannic acid in the wood. We recommend pre-drilling when you are working with hardwood. Because of the thread-cutting point, pilot holes are not required when you are working with softwood.

Wovar's wafer head screws have a large bearing surface and clamp force due to the 20 mm wide head. Furthermore, these screws are made of A4 stainless steel. A4 stainless steel screws are acid and rust-resistant. On top of that, these A4 stainless steel screws can cope with pool water and seawater. This makes them popular in coastal regions. 

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.
