Round HSS tube (AISC): HSS 4.500x0.237, HSS 6.625x0.280, HSS 10.000x0.375 dimensions + STEP/STL

What are the OD and wall of HSS 4.500x0.237 round tube? · Standard part · basis: AISC Shapes Database (v15.0 values): OD, tnom, tdes for every round HSS

Also called: hss 4.500x0.237, hss4.5x0.237, hss 6.625x0.280, hss 2.375x0.154, hss 3.500x0.216, hss 10x3/8, round hss dimensions, round hss sizes, hss round tube dimensions, round steel tube dimensions

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

length
101.6 mm

Notes

  • Round HSS is cold-formed round tube with an outside diameter in inches (HSS6.625x0.280 is 6.625 in OD, the same OD as NPS 6 pipe). It is sold to ASTM A500 with the nominal wall tnom; AISC uses the design wall tdes = 0.93 x tnom in strength calculations.
  • Files draw the OD and the nominal wall (inside diameter = OD - 2 tnom). The printed area uses the design wall, so the drawn area is about 7 % higher; the design-wall version of the same section matches the printed area within 2 %.
  • AISC pipe sizes (STD, XS, XXS) share the pipe OD; use schedule-40-pipe for NPS pipe. This page lists the HSS round sizes only.
  • Files are 4 in (101.6 mm) long extrusions along X; the section is in the YZ plane, axis at y = 0, z = OD/2.
  • 13 of the 128 sizes have files.
