HSS8×6×5/8 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.

HSS8×6×5/8 is a rectangular tube 8 in. by 6 in. with a 5/8 in. nominal wall.

At 50.81 lb per foot it is the heaviest of the 6 HSS8×6 sizes, which run from 17.08 to 50.81 lb/ft.

For strong-axis bending its section modulus is Sx = 28.5 in³ and its moment of inertia Ix = 114 in⁴, with a plastic modulus Zx = 36.1 in³.
