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 Stainless Steel Wood Screw Threaded Studs
316 stainless steel studs have excellent resistance to chemicals and salt water and may be mildly magnetic. Also known as hanger bolts, use them to hang, mount, and fasten parts to wood structures. Install with a stud driver or create wrench flats by threading two nuts onto the stud and jamming them together.
