SCREW BOLT FASTENING SYSTEM
CoNNECTIoN DETAILS
A commonly accepted, code-compliant method of deck construction allows
for carrying beams and notched 6x6 support posts
to be bolted together. According to the International
Residential Code (IRC R502.9), “where posts and
beam or girders construction is used to support floor
framing, positive connections shall be provided to
ensure against uplift and lateral displacement.” When
installed as shown in this bulletin, the 7" FastenMaster ThruLok restrains
against both of these forces equal to traditionally bolted connections with
a faster and easier method of installation.
