Cragar SS Lug Nut/Stud Engagement Question.

I’ve used the 61C Cragar SS on a 69 Barracuda Formula S in the past but with long studs. The lug nuts recommended are conical seat 60 degree. Anyone using these wheels and lug nuts on a car with standard stud length? I want to use on my stock 68 Barracuda but afraid there is not enough lug nut to stud engagement. Seems like these things would come loose. Also these are the drilled 5X4 bolt Cragar.

Thoughts? Thanks !!
