R608.5.2.2

Section R608.5.2.2 is titled 'Anchor bolts' and covers requirements for anchor bolts used to connect concrete walls to light-frame construction. The prescriptive diagrams for which these anchor bolts are intended, standards and grades that the bolts must conform to, the requirement for bolts to have heads, and an alternative allowance for threaded rod conforming to a standard with a nut installed on the concrete embedded end, in lieu of a bolt with a head is established. The purpose of this section is to prevent structural failure.

The model shows a bolt with a head and a nut, a threaded rod with a nut on one end, a loose nut, and a bookshelf full of codes and standards.
