Looking for a way to cut down on the time it takes you to cut a knee brace, or perhaps you don’t have the tooling to cut all those mortises for the tenons? How would you like a variation that simplifies the cutting but still gives you the strength and looks of traditional mortise and tenon joinery? This post and beam knee brace connection may be a great option for you to consider.
The joint utilizes fully threaded structural screws along with a 3/4″ housing. Two screws at each end, one from each side at 45 degrees each way holds everything together. We have found that a 1 1/4″ hole allows you to easily install the screws and gives you enough room for the blind pegs that give you that traditional look.
We use the Rothoblaas VGZ screws in 7mmx 180mm (7.077″) in our plans, kits, and designs.
