Posts (bases)
Posts form the base of many professional jewelry configurations. Trinity offers a complete range of threadless, internally threaded, externally threaded, and push-pin posts in multiple lengths and gauges. Designed for compatibility with standardized ends and attachments, all posts meet Canadian studio standards and are manufactured using biocompatible, safe materials.
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 to narrow results by material, gauge, coating, thread type, or availability. This section includes all jewelry post bases such as flat-back labret stems, internally threaded barbells, push-pin bases, and butterfly-style earstud stems.
Trinity bases follow European threading standards (0.8 mm internal). Threadless and push-pin styles are also included and are compatible with their corresponding attachments listed separately.
