Abstract
A threaded rod connector includes a housing having a cavity for receiving a threaded rod therein where the housing has a mouth for inserting the threaded rod into the cavity. A plurality of rod engagement wedge segments are disposed within the cavity where each of the plurality of rod engagement wedge segments has a rod contact surface for engaging the threaded rod. The housing has a tapered surface which delimits the cavity and which tapers towards the mouth for wedging the plurality of rod engagement wedge segments against the threaded rod. At least one of the rod contact surfaces is threadless and has a surface roughness of 7.0 μm or greater.
