The Subaru Flange Bolt (Part Number: 010110450) is a genuine OEM fastener designed for a variety of structural and exhaust-related mounting points across Subaru vehicles. Engineered to factory specifications, this bolt ensures proper clamping force, alignment, and long-term durability in critical components.
Commonly referred to as a flange bolt, exhaust bolt, or crossmember bolt, this hardware is used in applications such as engine mount crossmembers, exhaust components, and underbody brackets. Its integrated flange design helps distribute load evenly across the mounting surface, reducing the risk of loosening, vibration, or component damage over time.
Manufactured to Subaru’s strict OEM standards, this bolt provides reliable performance and is ideal for replacing worn, corroded, or missing hardware while maintaining factory fit and function.
