Ordered two of these to use with two other angle clamps I already had (another manufacturer bought from Home Depot). I used them to fasten 2 pieces of 2x4 wood together just to keep them secure while I drilled pilot holes for the screws. One of the brackets broke under shockingly little force. I only hand tightened and didn't even try to overtighten it. The other has worked well for this project and others I've done since, but I always try not to drag it out too much. amount of power.
