Dzus Fastener attachment spring for use with Dzus Fasteners.

• EHF5 type ejecting fasteners use S5 springs
• EHF6 type ejecting fasteners use S5 springs

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

• Add together the thicknesses of both panels to be fastened and the spring clearance.
• Subtract spring deflection (0.047" for EHF5 and 0.062" for EHF6).
• Then select the fastener with the nearest shaft length.
