Hex Nuts Use a wrench or box wrench to tighten. There are three kinds of hexagonal nuts: types 1, 2, and 3. Type 1 is the most commonly used and what is generally referred to when speaking of "hexagon nuts". Type 1 nuts are chamfered on only one side, while type 2 nuts are chamfered on both sides. Type 3 nuts are thinner.
