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.
