Cycle Life

50

Cycle Life is the number of cycles (openings and

closings) that the fastener is subjected to while

maintaining 50% or greater ofthe original peel

values.

Note

Long Term Static Load: Conditions such as temperature variations, engagement area, closure pressure and vibrations or side to side movement after engagement or

exposure to prolonged periods of moisture or other environmental factors can a ect the closure strength and long term static load performance. Fasteners may slip or

creep in the direction of the static load forces when subjected to static loads at temperatures or weights greater than indicated. The user is responsible for designing

the amount of fastening area based upon the speci c conditions for the application. Four square inches of fastening area per pound of static load is suggested as a

starting point for such evaluations.
