rolled thread bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Mark,

There is a new DSA Interpretation of Regulations (IR) that is in draft form
right now that deals with bolts in wood members, and it will prohibit the
use of "bolts with reduced diameter body" per ASME 18.2.1.  The confusion
may stem from terminology: my understanding is that the term "cut thread
bolt" seems to be used commonly (and incorrectly) as describing both cut
thread AND ROLLED THREAD BOLTS that have full body diameter.  The term
"rolled thread bolt" is commonly used to describe the reduced diameter body
bolt.

I am not aware of any DSA policy that prohibits the use of all rolled thread
bolts (as describing a manufacturing process), just the ones with reduced
diameter body.

Thanks for the information =


With regards to the recommendations to allow rolled threads, that is not =
an
option since the agency that checks California public schools has ruled
that rolled threads are not acceptable.  Thus on school jobs we have to
follow the  rules......................
