Self-ejecting fasteners are designed for use on curved or contoured surfaces where ejection of the fastener is essential for removal of the top panel. The ejecting mechanism also gives an instant signal that the fastener is unlocked. EHF self-ejecting fasteners are available with flush head only. EHF5 ejecting fasteners use ‘S5’ springs and EHF6 use ‘S6’ springs. All EHF fasteners are zinc plated mild steel.

To calculate the correct pairing of fastener and spring use the following formula:

Add together the thickness of both panels to be fastened and the spring clearance (Dim H ). Subtract spring deflection ( 0.047” for 5 series, 0.062” for 6 series ). Then select the fastener with the nearest shaft length ( Dim L ).
