Questions about this item

What voltage does the 35 kV rating actually support in a crimped copper lug?

The lug is rated for a maximum of 35 kV when crimped to stranded copper wire up to 2 AWG using the correct die code 10 tool.

What stud size and hole spacing does the single-hole tongue require?

The straight tongue has a 0.63 in width and one hole sized for a 1/4 in stud; there is no centre-to-centre dimension because only one hole is present.

How do I crimp the chamfered barrel correctly and what common step is missed?

Use a die code 10 crimper on the 0.42 in outside-diameter barrel, insert the stripped conductor fully into the 0.3 in inside diameter, and do not skip the full-cycle compression that seats the lug flush.
