Features & Benefits
- Elimiates all radial clearance.
- Creates a rigid joint.
- Provides hole alignment and repeatability.
- Provides high reusability.
- Useable in applications where access is limited to one side, or a blind hole is required.

Special Options
- Lanyard - To secure the removed fastener near installation hole to prevent loss and provide for easier installation.
- Lock Ring - A bushing segment that is designed to provide limited expansion greater than the hole diameter. This segment is located outside the hole to enhance the ability of the fastener to resist tensile loads.
- Impedance Ring - Prevents loss of the fastener from the hole even if radial tightness is lost.
