I have attached a 10x22 shed style room to the rear gable end of my barn. The rafters are 4x6 @24" o/c. I have cut step lap rafter seats on both the wall plate and the upper girt that suports the upper end of the rafter. The rafters are locked in and fit quite nicely. I need to fasten down the rafters to the plate and girt. I purchased 8" TimberLok hex drive screws, but I would like to use a more traditional method of fastening, ie, white oak pegs. I am not sure how to do this. Is the peg hole drilled on an angle and is the top of the peg square to help lock it in? Any help would be appreciated. Thanks, John...
