The shear load of a spanclamp that is shown in the catalog is always static load.

The shear strength of 3000N is the static load of part SCQTRHD0620

We do not have any data of dynamic loads because there are countless cases.

And the 3000N shear strength does not have any safety rate, the fastener can brake if it receives 3000N.

When we tested the life cycles without any loads, the fastener worked more than 30000 cycles.

We just clamped and unclamped the fastener.

These are all data we can provide to you.

We suggest testing with some pieces in the actual application to all customers.

extra note:

we are developing another serie with a static shear load of 6000N, We have done calculation simulations with engineering software and came to the following conclusion.  The fastener we are designing can have 4000N up to 1500 cycles, however if the panel thicknesses are smaller it can only do 150 cycles.  So it all depends on the number of cycles you do the load.

We do not want to hold any liability to the dynamic load you exercice, so please test this into your own application.
