Simplified numerical characteristic capacities values are based on load duration and service class assumption (Instantaneous, Service class 2, kmod = 1.1). For other load duration, service class and fasteners, please refer to ETA-07/0285.

For HTT31, 4 CSA5.0x50 must always be installed on the bottom extremity of the oblong holes to reach the capacities given in the table. For other fasteners in these holes, the calculation shall be calculated according to ETA.
