Re: L-shaped A490 Anchor Bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next]
F1554 Gr 36 and Gr 55 with Supplementary Requirement S1 are weldable. We have been tacking nuts in the shop for years and no one has complained about the rod rotating when the column is erected and the top nut tightened.

If you have some material that is not weldable, a jam nut can be used. Properly installed, the nut will not rotate.

"Bad form" because...?

The Gr 36 material is weldable as are the nuts. I'm always willing to
entertain new ideas of course but in our jobs - petro/industrial - we have a jillion anchor bolts. This is a cost effective solution.

Also bad form to tack weld nuts to stop rotation. You can use ANCO nuts.
Just listened to a discussion of this all in Houston in the last three
