any body ever used these.

they are basically a washer that goes in between two pieces of wood that get bolted together to increase the resistance to shear forces



Figure @8-44.—Shear @plate @and @shear-plate @joints.

I havnt seen them used much and couldn't purchase them anywhere (might be called a different thing here). a few references to them in standards but thats it.

I am bolting some rafters to bottom cords and figured they are cheap and easy to throw in there and might just make it a bit stronger
