Straight Barbells
This section features straight barbells — a core staple in professional body piercing. Commonly used for tongue, nipple, and industrial piercings, straight barbells are also selected for bridge, ear cartilage, and other applications where stability and balanced pressure are required. Trinity offers threadless, internally threaded, and externally threaded models in a variety of lengths and gauges. All pieces are precision-machined from biocompatible materials and meet Canadian studio standards.
Important: All threaded components (internal and external) follow the European standard sizing system and may not be compatible with products from suppliers using U.S. thread sizes.
Straight barbells are a versatile choice in body piercing, widely used in tongue, nipple, and industrial placements. This subcategory includes internally and externally threaded styles as well as threadless options, available in multiple lengths and end types to support healing or aesthetic requirements.
All threaded models adhere to the European threading standard (0.8 mm internal), ensuring cross-compatibility with Trinity attachments. Please confirm thread compatibility before combining with components from other suppliers.
Use the filters on the left to narrow by material, gauge, coating, thread style, or availability. For placement guidance and anatomy-specific sizing tips, refer to our Product Info & Sizing or Certifications pages.
