The 30114a is 4 circuit and the 30116a is 6 circuit. Hence the 4 and 6 at the end of the number.

If your wire nuts loosen up, then you're installing them wrong. Tape isn't solving the problem, it's just masking poor quality work.
Electrical tape is notorious for shrinking over time or with heat, and loosing its stick. You come back to a gooey mess if you need to service the work later.
When was the last time you looked at the work of a professional electrician and saw taped wire nuts?
