Three Axes of Every Screw on Your Bench

Ever stared into a drawer of nearly identical silver screws, knowing the one you need is in there somewhere — but you can't name it, so you can't order it? This episode builds a mental map of the three-axis fastener taxonomy: thread form (M-sizes and the imperial trap of #6-32), head style (pan, flat, button, socket cap), and drive type (Phillips, Pozidriv, Torx, hex). Once you can name a screw, you can stock it, source it, and never be dead in the water again.
