7/16" - 20 is UNF(fine), 7/16"-14 is UNC(course)

Tap you need is 7/16 -20 UNF.

7/16" is bolt diameter(=.437"), 20 is threads per inch, UNF is Unified National Fine.

UNC is Unified National Course.

2.25 is the length of the bolt in inches, not the slope. You've been playing with metrics too much, haven't you
