A lock plate configured to retain a wear runner against a support may include a first retainer arm, a second retainer arm, and a web coupling the first and second retainer arms to one another. The first retainer arm, the second retainer arm, and the web may define a recess configured to receive a retainer pin associated with the wear runner. The first retainer arm and the second retainer arm may have a thickness configured to fit within a groove extending at least partially around the retainer pin, such that the lock plate holds the wear runner against the support on a side of the support opposite the lock plate.

A fastener system includes a fastener or nail for mounting objects on a surface and a corresponding plug for filling a hole left when the nail is removed from the surface. The nail and plug are formed of an engineering plastic, and may be formed from recycled materials. In embodiments, the nail and plug are joined by an arm which is easily broken away. In embodiments, the fastener and plug each have a plurality of flanges which provide strength and grip the surface.

In order to provide an anchor element for fastening an article to a further article, this anchor element being simple and inexpensive to produce and enabling an article to be fastened to a further article simply and reliably, it is proposed that the anchor element should include a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of the anchor element.
