Round bend U-bolts are typically used for attaching pipe or steel round bar to a round wood or steel post. Another common application is to hang wrought iron pipe in mechanical installations. They can also be embedded in concrete as anchor bolts. Square bend U-bolts are also available.

Portland Bolt does not provide U-bolts under 12” diameter.

Round U-bolts are typically dimensioned as follows:

Diameter (D) x Length (L) x Space between legs (C) x Thread (T)


Portland Bolt manufactures custom round bend U-bolts from 1/2″ through 4″ in diameter to virtually any ASTM specification. They are provided either plain finish or hot-dip galvanized. Other metals like 304 and 316 stainless steel U-Bolts are also manufactured. All operations, including the galvanizing process, are performed in-house.
