Thread pitch is the distance between each thread on the screw's shaft
hex head wood screw sizes. A finer pitch means more threads per inch or millimeter, resulting in a stronger hold but potentially requiring more torque to insert. Coarse threads, with fewer threads, provide quicker installation but may not be as secure.

One of the key benefits of using 40mm Tek screws is their durability. These screws are made from high-quality materials that are resistant to corrosion and rust, making them suitable for both indoor and outdoor projects. Whether you are working on a construction project or a home renovation, you can trust that these screws will provide a secure and reliable hold.
