2. Expansion Screws These screws are designed for concrete or masonry walls. When installed, they expand and grip the surrounding material as the screw is driven into it, creating a robust anchor point.

4. Reduced Risk of Damage Because these screws do not require a pilot hole, there is a decreased risk of splitting materials, particularly in wood.

The M in M20 signifies that it is a metric bolt, aligning with the International System of Units (SI). The number 20 denotes that the nominal diameter of the bolt is 20 millimeters. Foundation bolts are typically made from high-strength materials, such as structural steel, to ensure they can withstand substantial loads and resist environmental factors.

Tek screws are specialized screws designed with a drill point that allows them to drill through materials, eliminating the need for pre-drilling holes. Named after the brand Tek, which first popularized them, these screws are available in various sizes and materials—most commonly steel and stainless steel—making them suitable for a wide range of applications, including metal and wood cladding.
