Yor answer will not be "cut and dried" See the "Introduction" in SecI. The answer metengr has given you would be acceptable in my book.
RE: Section 1 Bolting
Does this interpretation help explain what deanc and metengr are trying to say? Just remember that the tables in PG-23.1 were moved to Section II Part D
Interpretation: I-77-14
Subject: Section I, Use of SA-193, SA-194, and SA-479
Date Issued: April 25, 1977
File Number: BC-75-417
Question: May SA-193 Bolting, SA-194 Nuts, and SA-479 Bars and Shapes be used in Section I construction? They are listed in Section II but do not appear in Section I paragraphs concerning allowable materials?
Reply: Bolting and nuts for bolts are not provided for specifically in Section I; i.e., they are not included in the stress Table PG-23.1. SA-193 Bolting and SA-194 Nuts meet the intent of Section I wherein it is provided in the Preamble that where complete details are not given, it is intended that the Manufacturer, subject to the approval of the Authorized Inspector, shall provide details of design and construction which will be as safe as otherwise provided by the rules in the Code.
