The M&M end, sometimes referred to as a smartie, is available in a variety of diameters and gauges from 18g through 00g.
M&M ends are great for tongue barbells because of their low profile.
The Anatometal brand stainless steel threaded M&M end is made from 316LVM
ASTM F-138 implant grade stainless steel.
The M&M is hand polished to perfection which
reduces the "wear and tear" on your piercing.
The M&Ms are countersunk for a seamless fit with a barbell.
All Anatometal brand threaded barbells have a self-locking feature built
into the threads which keeps the threaded ends in place.
Also, all Anatometal brand products are guaranteed to be free of defects
for a lifetime.
This threaded end will fit Anatometal brand internally threaded jewelry, but may not fit your other brand jewelry if purchased elsewhere (due to possible differences in threading). The gauge of the end must be the same gauge as jewelry it threads into.
