Attachments
Attachments include all decorative and functional ends designed to pair with threadless, internally threaded, externally threaded, or push-pin posts. Available in a range of gem-set, flat, textured, or specialty shapes, these components allow for complete customization of professional jewelry. All Trinity attachments are manufactured from biocompatible materials and meet Canadian studio standards.
Important: All threaded components use the European standard sizing system and may not be compatible with products from suppliers using U.S. thread sizes.
Use the filters to browse by material, gauge, coating, thread type, or availability. This category includes all decorative and functional jewelry attachments compatible with threadless, internally threaded, externally threaded, and push-pin bases.
Attachment compatibility depends on base type and threading style. Trinity attachments follow European threading standards (0.8 mm internal) and are precision-machined for secure fit and procedural safety.
For thread matching, sizing, and end-type compatibility, refer to our Piercing Info page.
