Simpson Strong-Tie HD3B Holdowns are a light duty bracket that is designed for a variety of uses including but not limited to shearwalls, braced-wall panels and other lateral applications. The holdown must be attached to the receiving member with 5/8" machine bolts. A minimum wood member thickness of 1-1/2" is required to reach the least allowable tension load. The bottom stud hole is 4-3/4" above the plate line so you can install the holdown flush with the plate without weakening the post or...

The Simpson Strong-Tie HD5B Holdown is a self jigging anchor that ensures the bottom bolt that attaches to the stud or post is seven times the diameter of the bolt. This is required so that the wood is not weakened from drilling too close to the end. However the anchor can still be installed raised above the sill plate if you desire. All the HDB style holdown anchors are designed to provide loads for intermediate-load-range shearwalls, braced wall panels and lateral applications. Base...
