Features & Benefits
- Creates a rigid joint.
- Provides high reusability.
- Eliminates wear in the joint.
- Eliminates all radial clearance.
- Provides quick installation and removal.
- Provides hole alignment and repeatability.
- Spring clip over pin nose retains handle in closed position.
- After initial adjustment for desired radial tightness, no tools are required for subsequent installation or removal in the same hole.
Special Options
- Lanyard - To secure the removed fastener near its 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.
- Dual locking features such as Cotter Pins, Lock Wires, etc.
- Metric sizes available on request.
Limitations
- Limited axial clamp-up capability.
- Less mechanical advantage available to achieve desired radial tightness than other EDF types.
- Nut must be adjusted for desired radial tightness at initial installation, and readjusted if used in another hole.
Standard Nominal Hole Sizes
- .375 through 1.500 inch
