Cast iron heads are durable, so they resist dents and scratches. However, they corrode more easily than zinc heads. Hardened cast iron heads are more durable and last longer than cast iron heads.

Welding Squares
Position your workpieces at the correct angle prior to welding. These squares have an extra-wide head, so you can clamp them in place.
2-axes squares set workpieces at a 45° or 90° angle. All have leveling tabs to ensure workpieces are aligned with one another. Those with joint access cutouts make it easier to reach joints, such as when welding and gluing.
3-axes squares set workpieces at a 90° angle along 3 axes at the same time.
Cast iron squares are scratch- and dent-resistant for durability. However, they are more susceptible to corrosion than aluminum.
