17. Check PDF packet page one for quick reference to page numbers… Start by drawing the following vertical rectangle.375x1.5

18. Offset top line down ½ D (0.1875) Draw a line from the blue circle intersection heading “@1<50” Mirror angled line over to the left side of the fastener and fillet, trim, extend, / erase.

19. Add slot for screw driver. Dimensions for height and width are 1/4D as noted in the book example.

29. Check last page of PDF for dimensions of steel plates. Top plate has a clearance hole for the fastener. Bottom plate is tapped (threaded)- See page 1 of PDF for page number referencing threaded holes Bottom plate has more threads cut than length of bolt, i.e. bolt can’t bottom out without fully tightening down. Pilot hole (pre-drilled hole before tapping can occur) extends lower than threads and has 80 degree angle (same as the twist drill bit that cut the hole). Dimensions can be “eye balled.”
