The load capacities specified in the table for the double sided shearing resistance (breaking strength) have been calculated or theoretically defined on the basis of DIN 50141.
At the same time, the endangered bolt cross-section S, according to a nearby sketch, was considered in two shear planes before breakage.
The values were arrived at by a series of tests whereby a limited number of levelling feet were subjected for a limited time to a vertical static load to the feet. In general, they do not constitute a warranty of condition.
The user must determine whether the product is suitable for the intended purpose. Environmental factors can influence the specified values.
An appropriate safety factor must be taken into account in the design.
