Excellent hardware and quality hardware. It depends on where it is mounted and on which material, but with wide screws are suitable wide washers or even a small counterplate.
This eye plate is too small for the Spi-Baum End fitting (50 x 2.5) by Pfeiffer. It would be good, if this would be in the product description, to which Endbeschlag-size fits the Augplatte.
