  • Anatometal uses only the best materials to be in contact with a piercing, either fresh or well healed
  • This stainless steel screw-on ball ring is made from ASTM F-138 certified implant grade stainless steel
  • All stainless steel products are machined from solid stock
  • Screw-on ball rings have a relatively substantial gap. Therefore, to avoid possible loss of the ring, Anatometal does not recommend them for genital piercings. They recommend a CBR instead.
  • All jewelry is hand polished to a mirror finish in order to offer the smoothest surface possible
  • Screw-on ball rings have the comfort and look of captives without the need of ring opening pliers.
  • The ring is internally threaded for the most comfortable insertion
  • Anatometal products are guaranteed to be free of manufacturing defects for a lifetime
See this chart for ball sizes. Top row is the inner diameter.

NOTE: Ball size may vary, especially for the smaller gauges (16g, 14g, and 12g). We only include this for a general reference, but manufacturing standards at Anatometal may change. If you receive a ring with a different ball size than listed, that is the standard ball size for that diameter. It is not considered a defect.

Fit, finish and comfort are superior. It has a great feeling of mass and reminds me that I have it in, every time I move.

I really love the way this 12g screw on ball piece looks and the awesomeness Anatometal does with their jewelry.  So much nicer I think then your ordinary captive bead rings with no fear of loosing the ball off the ring. Fairly easy to install as well. The mirror finish and smoothness is Anatometal's fine craftsmanship!  Thanks to SteelNavel.com for providing the best prices found on the net for quality body jewelry that I have found!  And I always have to say thanks to their customer service, for they are truly the best to be found!
