Metric Steel Hex Head Screws for Wood
Drive the pointed tip of these screws into soft material, such as wood and drywall. They are also known as lag bolts. Made from steel, they are strong and wear resistant, and have a zinc plating to protect the steel from rust in wet environments. The hex head provides a secure grip for wrenches, so you can tighten them in place. They meet DIN 571, which is an international standard for the dimensions of wood screws.
Drill a pilot hole slightly smaller than the screw to avoid splitting shorter boards. Screws with larger diameters are more likely to split your wood.

Metric Steel Phillips Rounded Head Drilling Screws for Metal
Drill a pilot hole, cut threads, and fasten in one motion with these metric-threaded screws. They're self-drilling, meaning they have a pointed tip that forms a pilot hole as they enter your material. As they turn, they also cut their own reusable threads, so you don’t need to drill and tap a hole first. Designed for fastening metal to metal, these screws are often used to install ducts and other assemblies where you can only access one side. The rounded head gives your project a finished look. Made of steel, they’re strong and wear resistant. They’re also plated with zinc to protect the steel from rust and extend the life of the screws. They meet ISO and DIN dimensional standards.
The miminum thread length may vary for screws with an overall length of 50mm or longer.
