Expandable Diameter Pin

Special Options

• Lanyard - To secure the removed fastener near installation hole to prevent loss and provide easier installation.
• Lock Ring - A bushing segment that is designed to provide limited expansion greater than the hole dia. 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 Locking Cam Handles.
• Metric sizes available on request.

Limitations

• Limited axial clamp-up capability.
• Less mechanical advantage available to achieve desired radial tightness than other EDF types.
• Core pin must be adjusted for desired radial tightness at initial installation and readjusted if used in another hole.

Standard Nominal Hole Sizes

• .1900 through 1.500 inch
