Abstract

A holdown connection including a single element holdown connector formed from a single metal sheet member requiring no welding for connecting a wood stud member to an anchoring means such as a concrete foundation or another structural member. Three sides of the connector are joined at 90° to each other along a rigid corner bend line. A holding seat member overlaps with a held seat member so that a held edge of the held seat member is in close engagement with a substantial portion of the length of the rigid bend line of the holding seat member. Bending slots formed in the back and side members are limited in length.
