Patent 7513083 was granted and assigned to Simpson Strong-Tie on April, 2009 by the United States Patent and Trademark Office.
A connection between a wall stud or post and an anchor bolt embedded in a concrete foundation, using a holdown connector that attaches to the anchor bolt and supports the wall stud or post above it. The holdown connector has a tapered bottom that allows it to rotate laterally, allowing the connection to act more purely in tension than is possible with a rigid connection.
