**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Single angles L(long leg) x (short leg) x thickness: L4x4x1/4 has two 4 in legs 1/4 in thick, L5x3-1/2x3/8 a 5 in leg and a 3-1/2 in leg. The long leg is d and the short leg b in the AISC database; both legs have the same thickness t.
- The thickness is taken from the designation (the database prints it rounded to two decimals). The root fillet is not printed: it is derived from the printed k (back of the leg to the toe of the fillet), r = k - t. The toe radius is not printed either, so toes are square.
- The files put the heel at the origin: the long leg runs along +y, the short leg along +z. 4 in (101.6 mm) long. Drawn area is within 4 % of the printed area on all of them.
- 31 of the 137 sizes (equal and unequal) have files; all sizes are in the table.
