Bases & Attachments

Browse Trinity's collection of professional body jewelry attachments and bases. Whether you need threadless ends, internally or externally threaded components, or Bioplast-compatible push-pin tops, each item is engineered for precision fit and safety.
Important: All threaded components (internal and external) use the European standard sizing system and may not be compatible with products from suppliers using U.S. thread sizes.

Use the filters on the left to narrow your results by material, gauge, coating, thread type, or availability. This category includes all jewelry bases and attachments, such as threaded ends, threadless ends, and specialized components.

All Trinity threaded jewelry uses European threading standards (0.8 mm internal). These components are not compatible with parts from brands using U.S. standard threading (0.9 mm).
