HSS6×6×5/8 square/rectangular HSS tube

Detailing dimensions and section properties from the AISC Shapes Database, 16th Edition. Values are shown to the nearest 1/16 in. as they appear on a shop drawing.

HSS6×6×5/8 is a square tube 6 in. by 6 in. with a 5/8 in. nominal wall.

At 42.3 lb per foot it is the heaviest of the 7 HSS6×6 sizes, which run from 9.86 to 42.3 lb/ft.

For strong-axis bending its section modulus is Sx = 18.4 in³ and its moment of inertia Ix = 55.2 in⁴, with a plastic modulus Zx = 23.2 in³.
