There are generally two types of hold-downs; the embedded strap and the anchor bolt hold down. Their function is to prevent the end of a shear wall from lifting off the foundation. The following are the principal elements necessary for hold downs to function properly:

  • A-Correct size of anchor bolt and/or hold down

  • B-Attached to the end stud by sufficient nailing or bolting

  • C-Nut tightened sufficiently on anchor bolt

  • D-Bolt holes drilled to proper size

  • Positioned properly at the end of the wall, adjacent to the end post

    Positioned at the proper distance from the edge of the foundation
