ABSTRACT:
Detachable filler strips for a threshing concave are retained by fastener assemblies which, for installation and securing of the filler strip, require access only to the inside of the concave. Each fastener assembly includes a resilient cylindrical body and a threaded fastener for axially compressing the body. In preparation for installation, fastener assemblies are installed in the filler strips and each tightened sufficiently to hold the resilient body nonrotatably (due to friction) against the filler strip. After installation, with the fastener assemblies extending outwards between the concave rods, further manipulation of the fastener from inside the concave expands the body diameter sufficiently to grip the rods and retain the filler strip in the concave.
