Introducing the SPAX Boardwalk Cylindrical Head Screws, designed for superior performance and durability. These screws are made from A4 316 Stainless Steel, ensuring long-lasting resistance to corrosion and the elements. The secondary thread provides increased strength and pull-out resistance, making them ideal for a wide range of applications. The T40 drive ensures easy installation and reduced cam-out, while the cylindrical head provides a smooth, professional finish.

BENEFITS

The small cylindrical head lies flush in the wood, achieving an appealing aesthetic finish.

Use: Wooden decking in outdoor areas

SECONDARY THREAD

The fixing thread consists of a main thread, which inserts into the substructure, and another thread below the head. This thread below the head ensures that the board remains securely in place on the substructure in all weather conditions. The smooth shank between the thread parts absorbs the movements of the board. No more re-fastening wooden boards that have become loose or creak too much!

A4 316 STAINLESS STEEL

Screws made of stainless steel A4 can basically do everything that a screw made of stainless steel A2 can. However, the higher alloy grade 4 also makes these screws resistant to saltwater and acid. This means that A4 stainless-steel screws are ideal for use in coastal areas. Here, the high salt content of the air and water would quickly cause A2 stainless-steel screws to rust. If you are planning to build wooden decking around a swimming pool, you should also remember that chlorinated water contains acid, too. What this means for you: Stainless-steel A4 screws offer the ultimate corrosion protection for all applications and we really mean all of them!
