A comment on the design: Having each hole as a combination bore and thread results in less potential thread engagement.  An engineering “rule of thumb” is 1X diameter for steel, 2X for aluminum.  The SMW plates fall short of that.  We know that – and in our testing, it has not a problem.  We roll form each aluminum thread and we test the results.  We are constantly tweaking and improving the design and manufacturing process.  Using a fastener that only engages a few threads could result in premature failure – a scenario exists with any threaded fastener.
