I recessed in a pan headed screw into the wood stringer because I was worried that a flat headed screw would split the end of the stringer.
Here you see the end brace. Most of the bolts have been cut down. The nuts are recessed into the wood so everything is flush.
Here you can see the recessed bolt head in the stringer. The long bolt is for a piece that I am going to add to strengthen the end braces.
