Ball pointed leveling feet GN 638 are suitable for universal use. The designs with plastic thrust pad prevent damage to sensitive surfaces. For applications in aggressive environments or higher loads, the stainless steel versions are to be preferred. The ball diameter d3 is smaller than the core diameter of the thread, with the effect that the screw can be screwed in on the ball side. The ball end can easily be pressed into the thrust pad and removed again, if necessary. Details regarding the static load capacity have been established by a series of tests but are indicative only. For these tests the loads have been placed vertically and centrally over the stud. At the measured load of 3.5 kN there was no remaining deformation visible on the thrust pad nor was there any breakage.
